MAX845 Datasheet (Maxim) - Isolated Transformer Driver for PCMCIA Applications

MAX845, Isolated Transformer Driver for PCMCIA Applications

The MAX845 provides an isolated power supply small enough to fit in thin PCMCIA cards and space-sensitive applications.

It drives a low-profile center-tapped transformer primary from a 5V or 3.3V DC power supply.

The secondary can be wound to provide any isolated positive or negative voltage at powe
