MAX1977

High-Efficiency / Quad Output / Main Power- Supply Controllers for Notebook Computers

MAX1977 Features

* include pulse skipping, which maximizes efficiency in light-load applications, and fixed-frequency PWM mode, which reduces RF interference in sensitive applications. The MAX1777 features a 200kHz/5V and 300kHz/3.3V SMPS for highest efficiency, while the MAX1977 features a 400kHz/5V and 500kHz/3.3V S

MAX1977 General Description

The MAX1777/MAX1977/MAX1999 dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems. The MAX1777/MAX1977/MAX1999 include two pulse-width modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V. These devices featu.
