Product Description
Features
The Cool-Power ZVS Isolated Converter Module Series
consists of high density isolated DC-DC converters
implementing Zero Voltage Switching topology.
• Efficiency up to 88%
The 28Vin Cool-Power series operates over a wide range input
of 16 V to 50 Vdc, delivering 50 W of output power, yielding
an unprecedented power density of 334 W/in3.
• Proprietary “Double-Clamped” ZVS Buck-Boost Topology
These converter modules are surface mountable and only
~.5" square in area achieving ~50% space reduction versus
conventional solutions.
• Very low profile (0.265 in)
• High switching frequency minimizes input filter
requirements and reduces output capacitance
• Proprietary isolated magnetic feedback
• Small footprint (0.57 in2) enables PCB area savings
• Wide input voltage range operation (16-50 Vdc)
• On/Off Control, positive logic
• Wide trim range +10/-20% most models

The switching frequency of 900 kHz allows for small input
and output filter components which further reduces the total
size and cost of the overall system solution. The output
voltage is sensed and fed back to the internal controller using
a high performance isolated magnetic feedback scheme which
allows for high bandwidth and good common mode
noise immunity.
The PI31xx-00-HVMZ series requires no external feedback
compensation and offers a total solution with a minimum
number of external components. A rich feature set is offered,
including output voltage trim capability, output over-voltage
protection, adjustable soft-start, over-current protection with
auto-restart, over and under input voltage lockout and a
temperature monitoring and protection function that
provides an analog voltage proportional to the die
temperature as well as shut down and alarm capabilities.
• Temperature Monitor (TM) &
Over-Temperature Protection (OTP)
• Input UVLO & OVLO and output OVP
• Over current protection with auto restart
• Adjustable soft-start
• 2250 Vdc input to output isolation
• Surface Mountable 0.87” x 0.65” x 0.265”
Applications
• Wide Temperature,
Aerospace & Defense Applications
• Space Constrained Systems
• Isolated Board Level Power
Package Information
• Surface Mountable 0.87” x 0.65” x 0.265” package

PI31xx-00-HVMZ
Functional Description
external soft-start circuitry. All faults will pull ENABLE low including
over temperature. If increased turn on delay is desired, the ENABLE
pin can be bypassed with a small capacitor up to a maximum
of 1500 pF.
Figure 41 — Picor PI31xx-00-HVMZ Shown With System Fuse, Filter,
Decoupling And Extended Soft Start
Input Power Pins IN(+) and IN(-)
The input power pins on the PI31xx-00-HVMZ are connected to the
input power source which can range from 16 V to 50 V DC. Under
surge conditions, the PI31xx-00-HVMZ can withstand up to 55 V DC
for 12.5 ms without incurring damage. The user should take care to
avoid driving the input rails above the specified ratings. Since the
PI31xx-00-HVMZ is designed with high reliability in mind, the input
pins are continuously monitored. If the applied voltage exceeds the
input over-voltage trip point (typically 53.5 V) the conversion
process shall be terminated immediately. The converter initiates softstart automatically within 80ms after the input voltage is reduced
back to the appropriate value. The input pins do not have reverse
polarity protection. If the PI31xx-00-HVMZ is operated in an
environment where reverse polarity is a concern, the user should
consider using a polarity protection device such as a suitably rated
diode. To avoid the high losses of using a diode, the user should
consider the much higher efficiency Picor family of intelligent
Cool-ORing® solutions that can be used in reverse polarity
applications. Information is available at vicorpower.com.
The PI31xx-00-HVMZ will draw nearly zero current until the input
voltage reaches the internal start up threshold. If the ENABLE pin is
not pulled low by external circuitry, the output voltage will begin
rising to its final output value about 80ms after the input UV lockout
releases. This will occur automatically even if the ENABLE
pin is floating.
To help keep the source impedance low, the input to the
PI31xx-00-HVMZ should be bypassed with (2) 4.7uF 50 V ceramic
capacitors of X7R dielectric in parallel with a low Q 100uF 63 V
electrolytic capacitor. To reduce EMI and reflected ripple current, a
series inductor of 0.2 to 0.47 uH can be added. The input traces to the
module should be low impedance configured in such a manner as to
keep stray inductance minimized.
ENABLE
The ENABLE pin serves as a multi-function pin for the
PI31xx-00-HVMZ. During normal operation, it outputs the on-board
4.9 V regulator which can be used for trimming the module up. The
ENABLE pin can also be used as a remote enable pin either from the
secondary via an optocoupler and an external isolated bias supply or
from the primary side through a small signal transistor, FET, or any
device that sinks 3.3 mA, minimum. If the ENABLE pin is lower than
2.35 V typical, the converter will be held off or shut down if already
operating. A third feature is offered in that during a fault condition,
such as output OVP, input UV or OV, or output current limit, the
ENABLE pin is pulled low internally. This can be used as a signal to
the user that a fault has occurred. Whenever the ENABLE pin is
pulled low, the TRIM/SS pin follows, resetting the internal and
TRIM/SS Pin
The TRIM/SS pin serves as another multi-purpose pin. First, it is used
as the reference for the internal error amplifier. Connecting a resistor
from TRIM/SS to SGND allows the reference to be margined down by
as much as -20%. Connecting a resistor from TRIM/SS to ENABLE
will allow the reference and output voltage to be margined up by
10%. If the user wishes a longer start up time, a small ceramic
capacitor can be added to TRIM/SS to increase it. It is critical to
connect any device between TRIM/SS and SGND and not -IN,
otherwise high frequency noise will be introduced to the reference
and possibly cause erratic operation. Referring to the figures below,
the appropriate trim up or trim down resistor can be calculated using
the equivalent circuit diagram and the equations. When trimming
up, the trim down resistor is not populated. When trimming down,
the trim up resistor is not populated. The soft start time is adjustable
within the limits defined by the data tables and has a default value of
500us to reach steady state. The internal soft start capacitor value is
10nF.

PI31xx-00-HVMZ
TM
The TM pin serves as an output indicator of the internal package
temperature which is within +/- 5 °K of the hottest junction
temperature. Because of this, it is a good indicator of a thermal
overload condition. The output is a scaled, buffered analog voltage
which indicates the internal temperature in degrees Kelvin. Upon a
thermal overload, the TM pin is pulled low, indicating a thermal fault
has occurred. Upon restart of the converter, the TM pin reverts back
to a buffered monitor. The thermal shutdown function of the PI31xx00-HVMZ is a fault feature which interrupts power processing if a
certain maximum temperature is exceeded. TM can be monitored by
an external microcontroller or circuit configured as an adaptive fan
speed controller so that air flow in the system can be conveniently
regulated.
SGND
The PI31xx-00-HVMZ SGND pin is the “quiet” control circuitry
return. It is basically an extension of the internal signal ground. To
avoid contamination and potential ground loops, this ground should
NOT be connected to -IN since it is already star connected inside the
package. Connect signal logic to SGND, not -IN.
Output Power Pins +OUT And -OUT
The output power terminals OUT(+) and OUT(-) deliver the
maximum output current from the PI31xx-00-HVMZ through the Jlead output pins. This configuration allows for a low impedance
output and should be connected to multi-layer PCB parallel planes
for best performance. Due to the high switching frequency, output
ripple and noise can be easily attenuated by adding just a few high
quality X7R ceramic capacitors while retaining adequate transient
response for most applications. The PI31xx-00-HVMZ does not
require any feedback loop compensation nor does it require any
opto-isolation. All isolation is contained within the package. This
greatly simplifies the use of the converter and eliminates all outside
influences of noise on the quality of the output voltage regulation
and feedback loop. It is important for the user to minimize resistive
connections from the load to the converter output and to keep stray
inductance to a minimum for best regulation and transient response.
The very small size footprint and height of the PI31xx-00-HVMZ
allows the converter to be placed in the optimum location to allow
for tight connections to the point of load. For those applications
absolutely requiring very tight regulation, contact Picor Engineering
at vicorpower.com for a remote sense application circuit which
can be used.
