General Description

The MAX16962R evaluation kit (EV kit) is a fully assembled

and tested circuit board that evaluates the MAX16962R

high-efficiency synchronous PWM step-down converter

with integrated high-side and low-side switches. The

EV kit output is configured to 3.3V and delivers up to

4A output current. The EV kit circuit operates at the IC’s

internally set 2.2MHz switching frequency.

The EV kit is designed to operate from a single DC

power supply that provides 3.5V to 5.5V and up to 4A

for normal operation. However, the IC has a 2.7V to

5.5V input voltage range. The EV kit, shipped with a

MAX16962RATEA/V+ in a 16-pin TQFN package with

exposed pad, provides enhanced thermal dissipation.

MAX16962R Evaluation Kit Evaluates: MAX16962R Quick Start Required Equipment • MAX16962R EV kit • 5.5V adjustable, 5A power supply • Electronic load capable of sinking up to 4A • Two digital voltmeters Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Verify that shunts are installed on jumpers JU1 (output enabled) and JU2 (forced-PWM mode).

MAX16962R Evaluation Kit Evaluates: MAX16962R Reconfiguring the EV kit circuit for a new output voltage may require replacing inductor L1 and capacitors C1–C4. To select new values for inductor L1 and capacitors C1– C4, refer to the Inductor Selection, Output Capacitor, and Input Capacitor sections in the MAX16962 IC data sheet. Enable Control (JU1) Jumper JU1 configures the EV kit output for turn-on/turnoff control. Install a shunt to enable the output. Remove the shunt to disable the EV kit output.
