Richardson RFPD, Inc. has announced the availability and full design support capabilities for a new transformer driver from Peregrine Semiconductor Corporation.

The PE22100 is a push-pull driver for small transformers in isolated power supply applications. The new device drives the primary of a center-tapped transformer from a 3.0 V or 5 V supply to deliver an isolated power supply.

The driver consists of an on-chip oscillator with frequency set by an external capacitor. The oscillator output is divided-by-two in frequency to create anti-phase clock signals that drive two power switches. The device also contains an internal current limit and thermal cutout.

It is designed for isolated power supply applications, including isolated data acquisition, industrial automation and instrumentation, isolated gate drivers and medical equipment.
