Overview

MAX1844 19-1993; Rev 3; 9/02 EVAALVUAAILTAIOBNLEKIT High-Speed Step-Down Controller with Accurate Current Limit for Notebook Computers General Description The MAX1844 pulse-width modulation (PWM) controller provides high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high-voltage batteries to generate low-voltage CPU core or chipset/RAM supplies in notebook computers.
Maxim’s proprietary Quick-PWM™ quick-response, constant-on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.
Efficiency is enhanced b...
