PE22100 Datasheet Transformer Driver

Manufacturer: pSemi (Peregrine Semiconductor)

Overview: PE22100 Document Category: Product Specification Transformer Driver for Isolated Power Supplies, 2.

General 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.
