MAX786集成电路（IC）的监控器规格书PDF中文资料

General Description

The MAX786 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. Other features include dual, low-dropout, micropower linear regulators for CMOS/RTC back-up, and two precision low-batterydetection comparators.
