1. Introduction
2. DC-DC Converter Features
The EC5SBW series offer 30 watts of output power in a
1.00x1.00x0.4 inches copper packages. The EC5SBW
series has a 4:1 wide input voltage range of 9-36 and
18-75VDC, and provides a precisely regulated output.
This series has features such as high efficiency,
1500VDC of isolation and allows an ambient operating
temperature range of –40°C to 85°C (de-rating above 55
°C). The modules are fully protected against input UVLO
(under voltage lock out), output over-current,
over-voltage protection and over-temperature and
continuous short circuit conditions. Furthermore, the
standard control functions include remote on/off and
adjustable output voltage. All models are very suitable for
distributed power architectures, telecommunications,
battery operated equipment and industrial applications.

6. Applications
5. Main Features and Functions
6.1 Recommended Layout PCB Footprints
and Soldering Information
5.1 Operating Temperature Range
The EC5SBW series converters can be operated by a
wide ambient temperature range from -40℃ to
85℃(de-rating above 55℃). The standard model has a
Copper case and case temperature can not over 105℃
at normal operating.
The system designer or the end user must ensure that
other components and metal in the vicinity of the
converter meet the spacing requirements to which
thesystem is approved. Low resistance and low
inductance PCB layout traces are the norm and should
be used where possible. Due consideration must also be
given to proper low impedance tracks between power
module, input and output grounds. The recommended
footprints and soldering profiles are shown as Figure 4.
5.2 Remote On/Off
The EC5SBW series allows the user to switch the
module on and off electronically with the remote on/off
feature. All models are available in “positive logic”
versions. The converter turns on if the remote on/off pin
is high (>3.5Vdc to 75Vdc or open circuit). Setting the pin
low (<1.2Vdc) will turn the converter off. The signal level
of the remote on/off input is defined with respect to
ground. If not using the remote on/off pin, leave the pin
open (converter will be on).Models with part number
suffix “N” are the “negative logic” remote on/off version.
The unit turns off if the remote on/off pin is high (>3.5Vdc
to 75Vdc or open circuit). The converter turns on if the
on/off pin input is low (<1.2Vdc). Note
that the converter is off by default.
5.3 UVLO (Under Voltage Lock Out)
Input under voltage lockout is standard on the EC5SBW
unit. The unit will shut down when the input voltage drops
below a threshold, and the unit will operate when the
input voltage goes above the upper threshold.
Note: Dimensions are in inches (millimeters)
Lead Free Wave Soldering Profile
5.4 Over Current Protection
300
Temperature ( C )
All models have internal over current and continuous
short circuit protection. The unit operates normally once
the fault condition is removed. At the point of current limit
inception, the converter will go into hiccup mode
protection.
5.5 Over Voltage Protection

Time (Seconds)
5.6 Over-Temperature Protection (OTP)
Note:
1. Soldering Materials: Sn/Cu/Ni
2. Ramp up rate during preheat: 1.4 ℃/Sec (From 50℃
to 100℃)
3. Soaking temperature: 0.5 ℃/Sec (From 100℃ to
130℃), 60±20 seconds
4. Peak temperature: 260℃, above 250℃ 3~6 Seconds
5. Ramp up rate during cooling: -10.0 ℃/Sec (From
260℃ to 150℃)
The EC5SBW series converters are equipped with
non-latching over-temperature protection. If the
temperature exceeds a threshold of 110°C (typical) the
converter will shut down, disabling the output. When the
temperature has decreased the converter will
automatically restart. The over-temperature condition
can be induced by a variety of reasons such as external
overload condition or a system fan failure.

6.4 Input Capacitance at the Power Module
VNL is the output voltage at 10% load
The converters must be connected to low AC source
impedance. To avoid problems with loop stability
source inductance should be low. Also, the input
capacitors (Cin) should be placed close to the converter
input pins to de-couple distribution inductance.
However, the external input capacitors are chosen for
suitable ripple handling capability. Low ESR capacitors
are good choice. Circuit as shown in Figure 5
represents typical measurement methods for reflected
ripple current. C1 and L1 simulate a typical DC source
impedance. The input reflected-ripple current is
measured by current probe to oscilloscope with a
simulated.

The value of line regulation is defined as:
Line.reg =

Where
VHL is the output voltage of maximum input voltage

In order to trim the voltage up or down one needs to

For example, to trim-up the output voltage of 5.0V module
(EC5SBW-24S05) by 10% to 5.5V, R trim-up is calculated as
follows:
Vo – Vo, nom = 5.5 – 5.0 = 0.5V
R1 = 2.32 KΩ
6.8 Output Capacitance
The EC5SBW series converters provide unconditional
stability with or without external capacitors. For good
transient response low ESR output capacitors should
be located close to the point of load. These series
converters are designed to work with load capacitance
to see technical specifications.
R2 = 2.32 KΩ
R3 = 0 KΩ
Rt = 8.2 KΩ,
Vr= 2.5 V
Rtrim − up = (
( 2.5 × 2.32)
− 1) − 8.2 = 1.08 (KΩ)
0.5 × 2.32
2.5 × 2.32 × ( 2.32 + 0)
) − 8.2 = 3.4(KΩ)
0.5 × 2.32
2.The value of R trim-down defined as:
Vr × R1
Rtrim − down = R1 × (
− 1) − Rt (K Ω)
(Vo , nom − Vo ) × R 2
Where
R trim-down is the external resistor in Kohm.
VO, nom is the nominal output voltage.
VO is the desired output voltage.
R1, Rt, R2, R3 and Vr are internal to the unit and are defined
in Table 1.
For example, to trim-down the output voltage of 5.0V module
(EC5SBW-24S05) by 10% to 4.5V, R trim-down is calculated
as follows:
VO,nom – Vo = 5.0 – 4.5 = 0.5V
R1 = 2.32 KΩ
R2 = 2.32 KΩ
R3 = 0 KΩ
Rt = 8.2 KΩ
Vr= 2.5 V

7. Safety & EMC
7.1 Input Fusing and Safety Considerations.
The EC5SBW series converters have not an internal fuse. However, to achieve maximum safety and system
protection, always use an input line fuse. We recommended a time delay fuse 6A for 24Vin models and 3A for 48Vin
modules. Figure 10 circuit is recommended by a Transient Voltage Suppressor diode across the input terminal to
protect the unit against surge or spike voltage and input reverse voltage.
