STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL or
PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER
© ABLIC Inc., 2002-2015
Rev.8.1_02
The S-8355/56/57/58 Series is a CMOS step-up switching regulator controller which mainly consists of a reference voltage
source, an oscillation circuit, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8355/57 Series) and
a PWM/PFM switching control circuit (S-8356/58 Series).
With an external low-ON-resistance Nch Power MOS, this product is ideal for applications requiring high efficiency and a
high output current.
The S-8355/57 Series realizes low ripple, high efficiency, and excellent transient characteristics due to its PWM control
circuit whose duty ratio can be varied linearly from 0 to 83% (from 0 to 78% for 250 kHz, 300 kHz, and 600 kHz models), an
excellently designed error amplifier and a phase compensation circuits.
S-8356/58 Series features a PWM/PFM switching controller that can switch the operation to a PFM controller with a duty
ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.
 Features
• Low voltage operation : Startup at 0.9 V min. (IOUT = 1 mA) guaranteed
• Low current consumption : During operation 25.9 A (3.3 V, 100 kHz, typ.)
During shutdown 0.5 A (max.)
• Duty ratio : Built-in PWM/PFM switching control circuit (S-8356/58 Series)
15 to 83% (100 kHz models)
15 to 78% (250 kHz, 300 kHz, and 600 kHz models)
• External parts : Coil, diode, capacitor, and transistor
• Output voltage : Selectable in 0.1 V steps between 1.5 and 6.5 V (for VDD / VOUT separate types)
Selectable in 0.1 V steps between 2.0 and 6.5 V (for other than VDD / VOUT separate types)
• Output voltage accuracy : 2.4%
• Oscillation frequency : 100 kHz, 250 kHz, 300 kHz, 600 kHz selectable

S-8355/56/57/58 Series
 Operation
1. Switching Control Types
1.1 PWM Control (S-8355/57 Series)
The S-8355/57 Series is a DC-DC converter using a pulse width modulation method (PWM) and features a low
current consumption.
In conventional PFM DC-DC converters, pulses are skipped when the output load current is low, causing a
fluctuation in the ripple frequency of the output voltage, resulting in an increase in the ripple voltage.
The switching frequency does not change, although the pulse width changes from 0 to 83% (78% for F, G, H, J, L,
M, N, P and Q types) corresponding to each load current. The ripple voltage generated from switching can thus
be removed easily through a filter because the switching frequency is constant.
1.2 PWM/PFM Switching Control (S-8356/58 Series)
S-8356/58 Series is a DC-DC converter that automatically switches between a pulse width modulation method
(PWM) and a pulse frequency modulation method (PFM), depending on the load current, and features low current
consumption.
The S-8356/58 Series operates under PWM control with the pulse width duty changing from 15 to 83% (78% for F,
G, H, J, L, M, N, P and Q types) in a high output load current area.
The S-8356/58 Series operates under PFM control with the pulse width duty fixed at 15%, and pulses are skipped
according to the load current. The oscillation circuit thus oscillates intermittently so that the resultant lower self
current consumption prevents a reduction in the efficiency at a low load current. The switching point from PWM
control to PFM control depends on the external devices (coil, diode, etc.), input voltage and output voltage. This
series are an especially highly efficient DC-DC converter at an output current around 100 A.
2. Soft Start Function
For this IC, the built-in soft start circuit controls the rush current and overshoot of the output voltage when
powering on or when the ON / OFF pin is switched to the “H” level.

3. ON/ OFF Pin (Shutdown Pin) (SOT-23-5 Package Products of S-8355/56/57/58 Series B, H, F, K, L, M, N and Q
Types)
ON / OFF pin stops or starts step-up operation.
Setting the ON / OFF pin to the “L” level stops operation of all the internal circuits and reduces the current
consumption significantly.
DO NOT use the ON / OFF pin in a floating state because it has the structure shown in Figure 13 and is not pulled
up or pulled down internally. DO NOT apply a voltage of between 0.3 V and 0.75 V to the ON / OFF pin because
applying such a voltage increases the current consumption. If the ON / OFF pin is not used, connect it to the VOUT
pin.
The ON / OFF pin does not have hysteresis.

During tON, the energy is stored in L and is not transmitted to VOUT. When receiving the output current (IOUT) from VOUT,
the energy of the capacitor (CL) is consumed. As a result, the pin voltage of CL is reduced, and goes to the lowest level
after M1 is turned ON (tON). When M1 is turned OFF, the energy stored in L is transmitted through the diode to CL, and
the voltage of CL rises rapidly. VOUT is a time function, and therefore indicates the maximum value (ripple voltage (VPP) )
when the current flowing through into VOUT and load current (IOUT) match.
Next, the ripple voltage is determined as follows.

1. Inductor
The inductance value (L value) has a strong influence on the maximum output current (IOUT) and efficiency ().
Figure 16 shows the relationship between the IOUT and  dependency on L of S-8355/56/57/58 series.

Figure 16 L Value vs. IOUT Characteristics, L Value vs.  Characteristics
The peak current (IPK) increases by decreasing L value and the stability of the circuit improves and IOUT increases. If L
value is decreased, the efficiency falls causing a decline in the current drive capacity for the switching transistor, and
IOUT decreases.
The loss of IPK by the switching transistor decreases by increasing L value and the efficiency becomes maximum at a
certain L value. Further increasing L value decreases the efficiency due to the loss of the direct current resistance of
the coil. IOUT also decreases.
A higher oscillation frequency allows selection of a lower L value, making the coil smaller.
The recommended inductances are a 22 to 100 H for B, E, and K types, a 4.7 to 47 H for F, G, H, J, L, and M
types, 3.0 to 22 H for N, P and Q types.
Be careful of the allowable inductor current when choosing an inductor. Exceeding the allowable current of the
inductor causes magnetic saturation, much lower efficiency and destruction of the IC chip due to a large current.
Choose an inductor so that IPK does not exceed the allowable current. IPK in discontinuous mode is calculated by the
following equation:
IPK 

3. Capacitor (CIN, CL)
A capacitor on the input side (CIN) improves the efficiency by reducing the power impedance and stabilizing the input
current. Select a CIN value according to the impedance of the power supply used.
A capacitor on the output side (CL) is used for smoothing the output voltage. For step-up types, the output voltage
flows intermittently to the load current, so step-up types need a larger capacitance than step-down types. Therefore,
select an appropriate capacitor in accordance with the ripple voltage, which increases in case of a higher output
voltage or a higher load current. The capacitor value should be 10 F or more.
Select an appropriate capacitor the equivalent series resistance (RESR) for stable output voltage. The stable voltage
range in this IC depends on the RESR. Although the inductance value (L value) is also a factor, an RESR of 30 to 500
m maximizes the characteristics. However, the best RESR value may depend on the L value, the capacitance, the
wiring, and the applications (output load). Therefore, fully evaluate the RESR under the actual operating conditions to
determine the best value.
Refer to the “3. Example of Ceramic Capacitor Application” (Figure 26) in the “ Application Circuit” for the
circuit example using a ceramic capacitor and the external resistance of the capacitor (RESR).
4. External Transistor
An enhancement (N-channel) MOS FET type or A bipolar (NPN) type can be used as the external transistor.

Figure 17 Circuit Example Using MOS FET (N-channel) Type
An N-channel power MOS FET should be used for the MOS FET. Because the gate voltage and current of the
external power MOS FET are supplied from the stepped-up output voltage (VOUT), the MOS FET is driven more
effectively.
A large current may flow during startup, depending on the MOS FET selection. So perform sufficient evaluation
using the actual devices. Also recommend to use a MOS FET with an input capacitance of 700 pF or less.
Since the ON-resistance of the MOS FET might depend on the difference between the output voltage (VOUT) and
the threshold voltage of the MOS FET, and affect the output current as well as the efficiency, the threshold
voltage should be low. When the output voltage is low, the circuit operates only when the MOS FET has a
threshold voltage lower than the output voltage.

A circuit example using the CPH3210 (hFE = 200 to 560) from Sanyo Electric Co., Ltd. As a bipolar transistor

A small Rb value can increase the output current, but the efficiency decreases. Since a current may flow on the
pulse and the voltage may drop due to wiring resistance or other factors in the actual circuit, therefore the
optimum Rb value should be determined by experiment.
Connecting the speed-up capacitor (Cb) in parallel with the Rb resistance as shown in Figure 18, decreases
switching loss and improves the efficiency.

5. VDD / VOUT Separate Type (For E, G, J, K, L, M, P and Q Types)
The E, G, J, K, L, M, P and Q types provides separate internal circuit power supply (VDD pin) and output voltage
setting pin (VOUT pin) in the IC, making it ideal for the following applications.
(1) When changing the output voltage with external resistance.
(2) When outputting a high voltage such as 15 V or 20 V.
Choose the products in the Table 24 according to the applications (1) or (2) above.

Cautions 1. This IC starts a step-up operation at VDD = 0.8 V, but set 1.8  VDD  10 V to stabilize the output
voltage and frequency of the oscillator. (Input a voltage of 1.8 V or more at the VDD pin for all
products with a setting less than 1.9 V.) An input voltage of 1.8 V or more at the VDD pin allows
connection of the VDD pin to either the input voltage VIN pin or output VOUT pin.
2. Choose external resistors RA and RB so as to not affect the output voltage, considering that there
is impedance between the VOUT pin and VSS pin in the IC chip. The internal resistance between
the VOUT pin and VSS pin is as follows :
(1) S-835xx18 : 2.1 to 14.8 M
(2) S-835xx20 : 1.4 to 14.8 M
(3) S-835xx30 : 1.4 to 14.2 M
(4) S-835xx50 : 1.4 to 12.1 M
3. Attach a capacitor (CC) in parallel to the RA resistance when an unstable event such as
oscillation of the output voltage occurs. Calculate CC using the following equation :

 Precautions
• Mount external capacitors, the diode, and the coil as close as possible to the IC.
• Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover rush current flows
at the time of a power supply injection. Because these largely depend on the coil, the capacitor and impedance of
power supply used, fully check them using an actually mounted model.
• Make sure that the dissipation of the switching transistor (especially at a high temperature) does not exceed the
allowable power dissipation of the package.
• The performance of this IC varies depending on the design of the PCB patterns, peripheral circuits and external parts.
Thoroughly test all settings with your device. Also, try to use the recommended external parts. If not, contact an ABLIC
Inc. sales person.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products
including this IC of patents owned by a third party.
