19-3626; Rev 0; 3/05 MAX8764 High-Speed, Step-Down Controller with Accurate Current Limit for Notebook Computers General Description The MAX8764 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 by an ability to drive very large synchronous-rectifier MOSFETs.
