描述 Description

The AIC2862 is a 2A synchronous-rectified Buck converter with integrated low Rds(on) power MOSFETs. The AIC2862, designed with a cur-rent-mode control scheme, can convert wide in-put voltage to the adjustable output voltage to provide excellent output voltage regulation. It is stable with low ESR output ceramic capacitors.

For high efficiency over all load current range, the

AIC2862 is equipped with an automatic PSM/PWM modeoperation. At light load, the IC operates in the PSM (Pulse Skipping Mode) to reduce switching losses. At heavy load, the IC works in PWM mode to provide high efficiency and excellent output voltage regulation.

The AIC2862 is also equipped with softstart and whole protections (under-voltage, over-voltage, over-temperature, short circuit and current-limit) into a single package.

This device, available in SOP-8 package, provides a very compact system solution with mini-mal external components and PCB area.
