MAX17595 Evaluation Kit Evaluates: MAX17595 as Flyback Converter General Description Features The MAX17595 evaluation kit (EV kit) is a fully assembled S 85V AC to 265V AC or 120V DC to 375V DC Input and tested circuit board that contains MAX17595 peak- Range current-mode controller for a flyback regulator. The EV S 15V DC at 1.5A Isolated Output Voltage kit is configured for an isolated 15V DC output voltage S Galvanic Isolation Up to 3500V RMS that can supply up to 1.5A current. The line input voltage S 120kHz Switching Frequency range is from 85V AC to 265V AC or 120V DC to 375V DC. S Efficiency Up to 86% The EV kit demonstrates low quiescent current and effi- S Low-Cost Flyback Design ciency up to 86%. This high efficiency is achieved by S Proven PCB Layout using a single-transistor (MOSFET) flyback converter S Fully Assembled and Tested 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 Ordering Information appears at end of data sheet. 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.
