PE22100 Document Category: Product Specification Transformer Driver for Isolated Power Supplies, 2 MHz Features Push pull driver for small transformers Operates off a 3.0V or 5V supply Adjustable switching frequency up to 2 MHz Current limit protection Over-temperature protection Packaging – 2 × 2 × 0.5 mm QFN Applications Isolated interface power supply Isolated data acquisition Industrial automation and instrumentation Isolated gate drivers Medical equipment Product 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. The oscillator output is divided by two in frequency to create anti-phase clock signals that drive ...
