MAX1993 - Quick-PWM Step-Down Controllers

Download the MAX1993 datasheet PDF. This datasheet also covers the MAX1992 variant, as both devices belong to the same quick-pwm step-down controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX1992/MAX1993 pulse-width modulation (PWM) controllers provide high-efficiency, excellent transient response, and high DC output accuracy.

The devices step down high-voltage batteries to generate lowvoltage CPU core or chipset/RAM supplies in notebook computers.

19-2661; Rev 1; 9/05 MAX1992/MAX1993 Quick-PWM Step-Down Controllers with Inductor Saturation Protection and Dynamic Output Voltages General Description The MAX1992/MAX1993 pulse-width modulation (PWM) controllers provide high-efficiency, excellent transient response, and high DC output accuracy. The devices step down high-voltage batteries to generate lowvoltage 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 the ability to drive very large synchronousrectifier MOSFETs.
