General Description

The MAX17536 3.3V output evaluation kit (EV kit) provides

a proven design to evaluate this high-voltage, high-efficiency,

synchronous step-down DC-DC converter. The EV kit is

preset for a 3.3V output at load currents up to 4A and features a

450kHz switching frequency for optimum efficiency and

component size. The EV kit features adjustable input,

undervoltage lockout, adjustable soft-start, open-drain RESET

signal, and external frequency synchronization.

Features

● Operates from a 4.5V to 60V Input Supply

● 3.3V Output Voltage

● Up to 4A Output Current

● 450kHz Switching Frequency

● Enable/UVLO Input, Resistor-Programmable UVLO

Threshold

● Adjustable Soft-Start Time

● MODE Pin to Select Among PWM, PFM, or DCM

Modes

● Open-Drain RESET Output

● External Frequency Synchronization

● Overcurrent and Overtemperature Protection

● Proven PCB Layout

● Fully Assembled and Tested

Quick Start

Recommended Equipment

● MAX17536EVKITA#

● 4.5V to 60V, 10A DC input power supply

● Load capable of sinking 4A

● Digital voltmeter (DVM)

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation.

Caution: Do not turn

on power supply until all connections are completed.

1) Set the power supply at a voltage between 4.5V and

60V. Disable the power supply.

2) Connect the positive terminal of the power supply to

the VIN PCB pad and the negative terminal to the

nearest PGND PCB pad. Connect the positive terminal

of the 4A load to the VOUT PCB pad and the negative

terminal to the nearest PGND PCB pad.

3) Connect the DVM across the VOUT PCB pad and

the nearest PGND PCB pad.

4) Verify that shunt is installed across pins 1-2 on jumper

JU1 (see Table 1 for details).

5) Select the shunt position on JU2 based on the

intended mode of operation (see Table 2 for details).

6) Turn on the DC power supply.

7) Enable the load.

8) Verify that the DVM displays 3.3V
