General Description

The MAX783 is a system-engineered power-supply controller for notebook computers or similar battery-powered equipment. It provides two high-performance step-down (buck) pulsewidth modulators (PWMs) for +3.3V/+5V and dual PCMCIA VPP outputs powered by an integral flyback winding controller. Other functions include dual, low-dropout, micropower linear regulators for CMOS/RTC back up, and two precision lowbattery-detection comparators.
