AP3410 - BCD Semiconductor

AP3410 1.5MHz Synchronous Step-down DC-DC Converter

The AP3410 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 MOSFET switchers. The oscillator and timing capacitors are all built-in providing an internal switching frequency of 1.5MHz that allows the use of small surface mount inductors and capacitors for.
