Dual Step-Down Controllers with Saturation Protection, Dynamic Output, and Linear 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 puters. 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,...
