MAX13256EVKIT# Datasheet PDF - Maxim Integrated

●The MAX13256EVKIT# from Maxim Integrated Products is an evaluation kit for MAX13256 36V H-Bridge transformer driver for isolated supplies. The MAX13256 H-bridge transformer driver provides a simple solution for making isolated power supplies up to 10W. The EV kit operates from an 8V to 36V DC power source and the on-board 1:1 turns-ratio transformer from HALO sets the output voltage range from 6.8V to 34.8V with a 300mA current limit. The EV kit provides greater than 90% overall efficiency at +24V between 2.2W and up to 8.3W output power using an H-bridge DC to DC converter topology. Input ripple current and radiated noise are minimized by the inherent balanced nature of the design with no interruption in the input current. Undervoltage lockout (UVLO), adjustable current limit and thermal shutdown provide for a robust 10W isolated supply. The surface mount transformer provides galvanic isolation with output powered from a full wave rectifier circuit, reducing output voltage ripple.
