Product Details

The MAX258 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the MAX258 push-pull transformer driver. The EV kit operates from a single 3.0V to 5.5V supply and the on-board 1CT:1.3CT turns-ratio transformer sets the output voltage.
The EV kit provides up to 90% overall efficiency at 5V with up to 2.3W output power using a push-pull isolated DC-DC converter. Undervoltage lockout and thermal shutdown provide for a robust isolated supply. The surface-mount transformer provides galvanic isolation with the output powered from a push-pull rectifier circuit, reducing the output-voltage ripple.
The EV kit circuit is configured as a push-pull rectifier, with an output voltage that follows the input voltage. The EV kit is also configurable for other topologies including bipolar outputs and full-wave rectification.
