APW7322 SOP-8

2A, 5V, 1MHz Synchronous Buck Converter

APW7322/A is a synchronous buck converters with integrated 85mW high side and 75mW low side power MOSFETs. The APW7322/A with a current-mode control scheme can convert wide input voltage of 2.9V to 6V to the output voltage adjustable from 0.8V to 6V to provide excellent output voltage regulation. The APW7322/A 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 APW7322/A 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 in SOP-8, TDFN3x3-10 packages, provides a very compact system solution external components and PCB area.
