General Description
APW8830A is a 3A synchronous buck converter with integrated 75mΩ high side and 65mΩ low side power MOSFETs. The APW8830A, 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 APW8830A 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 APW8830A is also equipped with Power-on-reset, softstart, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available TDFN3x3-10, provides a very compact system solution external components and PCB area.
