MIC23254

MIC23254 4MHz Dual 400mA Synchronous Buck Regulator with Low Input Voltage and HyperLight Load™ General Description Features The MIC23254 is a low-input voltage, high-efficiency 4MHz dual 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 capacitors. MIC23254 operates from an input voltage down to 2.5V for low battery states. The MIC23254 has a tiny 2mm x 2mm Thin MLF® package that saves precious board space by requiring only 6 additional external components to drive both outputs up to 400mA each. The device is designed for use with a 1µH inductor and a 4.7µF output capacitor that enables a sub-1mm height. The MIC23254 has a very-low quiescent current of 33...
