High-Efficiency, Quad-Output, Main PowerSupply Controllers for Notebook Computers
General Description
The MAX8732/MAX8733/MAX8734 dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems.
The MAX8732/MAX8733/MAX8734 include two pulse-width 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.
