Product Details

The MAX845 evaluation kit (EV kit) is an assembled and tested isolated 5V power supply that meets PCMCIA height requirements. Two demonstration circuits are provided: a 100mA circuit that uses an industry-standard 78L05 regulator, and a 40mA circuit that uses a low-cost zener shunt regulator. Both circuits consist of a MAX845 IC (in the µMAX® package), a low-profile transformer, a half-wave rectified voltage doubler, and a regulator.
