Triple-Output Power-Supply Controller for Notebook Computers
MAX782
_______________General Description
The MAX782 is a system-engineered power-supply controller for notebook computers or similar battery-powered equipment.
It provides two high-performance step-down (buck) pulse-width modulators (PWMs) for +3.
3V and +5V, and dual PCMCIA VPP outputs powered by an integral flyback winding controller.
Other functions include dual, lowdropout, micropower linear
regulators for CMOS/RTC backup, and three precision low-battery-detection comparators.
High efficiency (95% at 2A; greater than 80% at loads from 5mA to 3A) is achieved through synch...
