MAX17595 Evaluation Kit

Evaluates: MAX17595 as Flyback Converter

General Description

The MAX17595 evaluation kit (EV kit) is a fully assembled

and tested circuit board that contains MAX17595 peak-

current-mode controller for a flyback regulator. The EV

kit is configured for an isolated 15V DC output voltage

that can supply up to 1.5A current. The line input voltage

range is from 85V AC to 265V AC or 120V DC to 375V

DC.

The EV kit demonstrates low quiescent current and effi-

ciency up to 86%. This high efficiency is achieved by

using a single-transistor (MOSFET) flyback converter

topology that operates at 120kHz switching frequency.

The surface-mount transformer has a tertiary winding to

power the IC after startup. An optocoupler, along with the

transformer, provides galvanic isolation up to 3500V

RMS

.

Warning: The EV kit is designed to operate with high

voltages. Dangerous voltages are present on this EV kit

and on equipment connected to it. Users who power up

this EV kit or the power sources connected to it must be

careful to follow safety procedures appropriately to work

with high-voltage electrical equipment.

Under severe fault or failure conditions, this EV kit may

dissipate large amounts of power, which could result in

the mechanical ejection of a component or of component

debris at high velocity. Operate this EV kit with care to

avoid possible personal injury.
