Description

Controller IC Chip - Synchronous-Rectified Buck Converter MOSFET APW7142 APW 7142 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0300)

The APW7142 is a 3A synchronous-rectified Buck con-verter with integrated 70mQ power MOSFETs. The APW7142, 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 APW7142 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 APW7142 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. In shutdown mode, the supply current drops below 3xA. This device, available in an 8-pin SOP-8 package, pro-vides a very compact system solution with minimal exter-nal components and PCB area.
