MAX17606 Synchronous Flyback

Evaluation Kit

General Description

The MAX17606 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates an isolated 15W

synchronous flyback DC-DC converter. The circuit uses

the MAX17606 secondary synchronous rectifier driver in

a 6-pin SOT23 package, as well as the MAX17597 peak

current mode flyback controller in a 16-pin TQFN package.

The EV kit circuit is configured to deliver an isolated +5V output

voltage and provides up to 3A of output current. The EV kit is

programmed to operate at a 200kHz switching frequency. An

optocoupler, along with the transformer, provides the galvanic

Quick Start

Recommended Equipment

● One 18V–36V DC, 2A power supply

● Load capable of sinking 3A

● Four digital multimeters (DMM)

● MAX17606_SYNC_FB EVKITA#

Warning:

1) Do not turn on the power supply until all connections

are completed.

2) Wear protective eye gear at all times.

3) Do not touch any part of the circuit with bare hands or

conductive materials when powered up.

4) Make sure all high-voltage capacitors are fully discharged

before handling.Allow 5 minutes after disconnecting input

power source before touching circuit parts.

Equipment Setup and Test Procedure

1) Set the power supply to +24VDC. Disable the power

supply output.

2) Connect the positive terminal of the power supply to the

PGND PCB pad. Connect the positive terminal of the 3A

the nearest GND0 PCB pad.

3) Connect two DMMs, configured in voltmeter mode,

across the input and output terminals to measure the

input and output voltage, respectively.

4) Connect two DMMs configured in ammeter mode at

the input and output to measure the input current and

output current.

5) Enable the power supply.

6) Verify that the output voltmeter displays 5V and the

output load current is 3A.

7) If required, vary the input voltage from 18V to 36V, the

load current from 0mA to 3A, and verify that the output

voltage is 5V.
