PE22100 Description
The PE22100 is a push pull driver for driving small transformers for isolated power supply applications. The PE22100 drives the primary of a center-tapped transformer, such as the 782100 family from Murata, from a 3.0V or a 5V supply to deliver an isolated power supply. The device consists of an on-chip oscillator whose frequency is set by an external capacitor.
