APW8827A
Active
3A 5V 1MHz Synchronous Buck Converter
Features
General Description
APW8827A is a 3A synchronous buck converter with integrated 75mΩ high side and 65mΩ low side power MOSFETs. The APW8827A design with a current-mode control scheme, can convert wide input voltage of 2.9V to 5.5V to provide excellent output voltage regulation. The APW8827A is equipped with an automatic Skip/PWM mode operation. At light load, the IC operates in the Skip mode to reduce the switching losses. At heavy load, the IC works in PWM mode. The APW8827A is also equipped with Power-on-reset, soft start, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available TDFN2X2-8, SOT-23-5 and SOT-23- 6 provide a very compact system solution external components and PCB area.
