3A, 12V, Synchronous-Rectified Buck Converter

The APW7145 is a 3A synchronous-rectified Buck con- verter with integrated 55mW Power MOSFETs The APW7145 designed with a current-mode control scheme, CAN convert wide input voltage of 4.3V to 14V to the output voltage adjustable from 0.8V to VIN to provide excellent output voltage regulation. For high efficiency over all load current range, the APW7145 is equipped with an Automatic Skip/PWM mode operation. At light load, the IC operates in the Skip mode, which keeps a constant minimum inductor peak current, to reduce switching losses. At heavy load, the IC works in PWM mode, which inductor peak current is programmed by the COMP voltage, to provide high efficiency and excel- lent output voltage regulation. The APW7145 is also equipped with power-on-reset, soft-start, soft-stop and whole protections (undervoltage, overvoltage, over temperature and current-limit) into a single package. In shutdown mode, the supply current drops below 3mA. This device, available in an 8-pin SOP-8P package, pro- vides a very compact system solution with minimal exter- nal components and PCB area.
