AP3431 Datasheet (BCD Semiconductor) - Synchronous Step Down DC-DC Converter

AP3431, Synchronous Step Down DC-DC Converter

The AP3431 is a high efficiency step-down DC-DC voltage converter.

The chip operation is optimized by peak-current mode architecture with built-in synchronous power MOS switchers.

The oscillator and timing capacitors are all built-in providing an internal switching frequency of 1MHz that allows the
