MIC23031 Datasheet 4mhz Pwm 400ma Buck Regulator

Manufacturer: Micrel Semiconductor (now Microchip Technology)

MIC23031 Overview

The MIC23031 is a high-efficiency 4MHz 400mA synchronous buck regulator with HyperLight Load™ mode. HyperLight Load™ provides very-high efficiency at light loads and ultra-fast transient response which is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very-low output ripple voltage throughout the entire load range with the use of small output...
