Description
The AP3432 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 portable product implementations. Additional features including Soft Start (SS), Under Voltage Lock Out (UVLO), Thermal Shutdown Detection (TSD) and short circuit protection are integrated to provide reliable product applications. The device is available in adjustable output voltage versions ranging from 0.8V to VIN when input voltage range is from 2.7V to 5.5V, and is able to deliver up to 2.5A.
