MAX25256EVKIT Driver Evaluation Kit

Analog Devices MAX25256EVKIT Driver Evaluation Kit is a fully assembled and tested PCB that contains the MAX25256 10W isolated H-bridge DC-DC converter. The evaluation kit operates from an 8V to 36V DC power source, and the onboard 1:1 turns-ratio transformer from HALO sets the output voltage range from 6.8V to 34.8V with a 215mA current limit. The Analog Devices kit provides greater than 90% overall efficiency at +24V between 2.2W and 8.3W output power using an H-bridge DC-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 a robust 10W isolated supply. The surface-mount transformer provides galvanic isolation with the output powered from a full-wave rectifier circuit, reducing the output-voltage ripple.
