• Manufacturer Part Number: MAX16955EVKIT#
• Description: Power Management Modules & Development Tools Evaluation kit for 3 6V High-Frequency St
• Manufacturer: Maxim Integrated Products

Note: Indicate that you are using the MAX16955 when contacting these component suppliers.
• MAX16955 EV kit
• 12V, 1A power supply
• An electronic load capable of sinking 1A (e.g.,HP6060B)
• Two digital voltmeters (DVMs)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Verify that a shunt is installed across pins 2-3 on
2) Verify that a shunt is not installed across jumper JU2
3) Connect the load across the OUT and PGND test
4) Connect the first DVM across the SUP and PGND test
5) Connect the second DVM across the OUT and PGND
6) Connect the power supply’s positive and ground

The MAX16955 EV kit is a fully assembled and tested
PCB that contains all the components neces sary to
evaluate the performance of the MAX16955 synchronous
PWM step-down controller. The device is available in a
16-pin TSSOP package and features an exposed pad for
thermal dissipation. The device has a 3.5V to 36V input
voltage range. The EV kit circuit is designed to operate
from a single DC power supply ranging from 6V to 36V.
The EV kit is configured to output 5V and provides up to
5A load current at the OUT and PGND test points. The
switching frequency is set to 400kHz using resistor R8.
The peak inductor current is set to 5.3A using resistor
R4. The EV kit can be configured to operate in forced
fixed-frequency PWM mode, low-quiescent current SKIP
mode, or external synchroniza tion using jumper JU1. The
EV kit features test points to evaluate the enable (EN)
feature and to monitor the BIAS output volta ge. A
red LED (D2) is available to monitor the power-good
(PGOOD) output signal.
