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. 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. The PE22100 is available in a 2 × 2 × 0.5 mm QFN package and is specified for operation from –40 °C to +125 °C.
The PE22100 is manufactured on Peregrine’s UltraCMOS® process, a patented advanced form of silicon-on-insulator (SOI) technology, offering the performance of GaAs with the economy and integration of conventional CMOS.
