Regulator
General Description
The MAX1540A/MAX1541 dual pulse-width modulation (PWM) controllers provide the high efficiency, excellent transient response, and high DC-output accuracy necessary for stepping down high-voltage batteries to generate low-voltage chipset and RAM power supplies in notebook computers.
The Maxim proprietary Quick-PWM™ controllers are free running, constant on-time with input feed forward.
This configuration provides ultra-fast transient response, wide input-output (I/O) differential range, low supply current, and ...
