MAX8732A - Main Power-Supply Controllers

Description

The MAX8732A/MAX8733A/MAX8734A dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems.

The MAX8732A/MAX8733A/MAX8734A include two pulsewidth modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V.

Features

  • include pulse skipping, which maximizes efficiency in light-load.

19-3711; Rev 0; 5/05 High-Efficiency, Quad-Output, Main PowerSupply Controllers for Notebook Computers General Description The MAX8732A/MAX8733A/MAX8734A dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems. The MAX8732A/MAX8733A/MAX8734A include two pulsewidth modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V. These devices feature two linear regulators providing 5V and 3.3V always-on outputs. Each linear regulator provides up to 100mA output www.DataSheet4U.com current with automatic linear-regulator bootstrapping to the main SMPS outputs.
