MAX1711开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF中文资料

General Description

The MAX1710/MAX1711 step-down controllers are intended for core CPU DC-DC converters in notebook

computers. They feature a triple-threat combination of ultra-fast transient response, high DC accuracy, and

high efficiency needed for leading-edge CPU core power supplies. 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.
