Introduction
The PI31xx-xx-EVAL1 evaluation board allows the user to test the basic operating principles of the
PI31xx series of high-density DC-DC power converters and experience the performance and value of
this solution compared to alternate conventional solutions. Each evaluation board is populated with
the components that could be used in a final design. It is not designed or intended to be used in
end‑product applications. Please read this document prior to the connection of test equipment and
refer to the product data sheet for device specifications, descriptions and characteristics. Remember to
follow good lab safety practices and use safety glasses at all times.
The PI31xx-xx-EVAL1 is configured to support one single input and one single output. Each board
offers pin-strap options for trimming the output voltage up and down, turning the converter on
and off and adding EMI system “Y” capacitors. Additional parts are included to compensate for line
impedance associated with long leads from the bench power supply to the converter. Additional
component footprints are made available to allow the user to test different design configurations that
may be required to meet their end needs. Kelvin-type test points are included to allow for easy and
convenient connections of testing instruments for evaluation of efficiency, line/load regulation and
transient response. A low-impedance oscilloscope connection using a Johnson jack is included for
ripple measurement and evaluation of the output voltage during transient events. Each demo board is
equipped with a heat sink to allow high-power operation with a small amount of air flow and to allow
operation of the board over various temperature extremes.

PI31xx Series Product Description
The PI31xx operates over a wide-range input, delivering 50 or 60W output power depending on the
individual model number. The PI31xx series is available in a space-saving surface-mountable
0.87 x 0.65 x 0.265in Power-System-in-a-Package (PSiP), achieving ~50% space reduction versus
alternative solutions.
The switching frequency of 900kHz 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 proprietary isolated magnetic feedback scheme which allows for high
bandwidth and good common-mode noise immunity.
The PI31xx 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 +10%, –20% output
voltage trim capability (depending on the model number), remote enable, overvoltage protection,
adjustable soft start, overcurrent protection with auto restart to protect against both short-circuit and
overload, and over and under input voltage lockout. A unique temperature monitor and protection
circuit is included that provides an analog voltage proportional to the internal die temperature, as well
as overtemperature shut down, restart and overtemperature-fault alarm signal.
Board Connections
1. Connect Test Equipment
a. Connect the input DC power supply to the target board as shown in Figure 6. The negative
terminal should be wired to –IN and the positive terminal should connect to the positive
terminal of the DMM wired as a DC Ammeter. Be sure that the proper sized wires are used to
allow minimum voltage drop for a maximum input current of up to 4A. Use ring lugs mated
to the included fasteners on the evaluation board. If your input power supply has remote
sense capability, it can be wired to the INN and INP test points if desired. Connect the positive
terminal of the DMM to the +IN lug on the evaluation board.
b. Connect the primary side DMM (for measuring the input voltage) to INN and INP respectively.
c. Connect the oscilloscope as shown in Figure 6 if you are planning to measure both primary and
secondary signals at the same time. If you do not have an isolated differential amplifier, it is
important to note that simultaneous measurement of both primary and secondary referenced
signals using an oscilloscope with a grounded chassis is not recommended, as it will short circuit
the primary to secondary isolation barrier. Floating the oscilloscope is also not recommended
due to the large capacitance introduced by this long standing practice. The best practice is to
use an isolated differential amplifier or use an oscilloscope with isolated channels. That is, the
input returns are isolated from each other and earth ground.
d. Connect the output DC DMM to the test points OUTN and OUTP. These test points are done in
a Kelvin type manner so that they have no high current flowing in them.
e. Connect the DC Load to the output lugs OUT+ and OUT–. It is critical for this connection
to be low inductance.

2. Default Pin Strap Configuration
a. Ensure the pin straps are in the following default locations before proceeding:
nnENABLE = Not Used (enabled)
nnTRIM_UP = Not Used
nnTRIM_DN = Not Used
nnOPT1 = Not Used
nnOPT2 = Not Used
3. Pin Strap Functions
a. ENABLE – Adding a strap on this pin will cause the converter to shut down.
b. TRIM_UP – Adding a strap in this location will adjust the output voltage up by 10%.
c. TRIM_DN – Adding a strap in this location will adjust the output voltage down by 10%. Only
one strap can be connected at a time. If both trim straps are out, the output voltage should be
set to the model’s nominal output.
4. Trimming and Soft Start
a. For those customers who wish to trim to another voltage by changing the preset trim resistors
to another value, the trim equation shown in Figure 2 can be used:
RLOW = (–VDESIRED) •
Figure 2
PI31xx trim equation
RHIGH = (–RREFI) •
RREFI
(–VOUT_NOM) + VDESIRED
(–VOUT_NOM) • VERO + VDESIRED • VREF
VREF ((–VOUT_NOM) + VDESIRED)
Where:
R1 = RLOW
R3 = RHIGH
VERO = 4.9 and
VREF can be found in the appropriate model datasheet.
Figure 3 shows an equation for soft-start configuration where C7 = CREF

Thermal Considerations
The PI31xx-xx-EVAL1 is supplied with optional heat sinks. At present, Vicor offers four different heat
sink options to accommodate the customers space and cooling needs. Heat sinks are available in two
sizes, one with 6.3mm fins and the other with 11mm fins. Each of those heat sinks can be ordered with
a specific air flow direction in mind, both cross flow and longitudinal are supported. Please refer to the
product website www.vicorpower.com for more information.
