Product Summary
The MAX1711EEG-T is a step-down controller. It be intended for core CPU DC-DC converters in notebook computer. The MAX1711EEG-T feature a triple-threat combination of ultra-fast transient response, high DC accuracy, and high efficiency needed for leading-edge CPU core power supplie. Maxim 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. Applications are (1)Notebook Computers; (2)Docking Stations; (3)CPU Core DC-DC Converters; (4)Single-Stage (BATT to VCORE)Converters; (5)Two-Stage (+5V to VCORE)Converters.
