Product Details

The MAX17598 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains a peak-current-mode controller for an active-clamp forward regulator. The EV kit is configured for an isolated 3.3V DC output voltage that can supply up to 8A of current. The input voltage range is from 36V DC to 72V DC.
The EV kit demonstrates low quiescent current and efficiency up to 93.6%. High efficiency is achieved by using an active-clamp forward converter topology, with self-driven synchronous secondary MOSFETs on the output side. The EV kit is configured to operate at a 350kHz switching frequency. The surface-mount transformer has a bias winding to power the IC after startup. An optocoupler along with the transformer provide galvanic isolation between input and output, up to 3000VRMS.
Warning: The EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on the 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.
