Overview
19-2224; Rev 3; 12/03
500kHz Multi-Output, Low-Noise Power-Supply Controllers for Notebook Computers
General Description
The MAX1901/MAX1902/MAX1904 are buck-topology, step-down, switch-mode, power-supply controllers that generate logic-supply voltages in battery-powered systems.
These high-performance, dual/triple-output devices include on-board power-up sequencing, power-good signaling with delay, digital soft-start, secondary winding control, low dropout circuitry, internal frequency-compensation networks, and automatic bootstrapping.
Up to 97% efficiency is achieved through synchronous rectification and Maxim’s proprietary Idle Mode™ control scheme.
Efficiency is greater than 80% over a...
