MIC23031 4MHz PWM 400mA Buck Regulator with HyperLight Load General Description Features The MIC23031 is a high-efficiency 4MHz 400mA Input voltage: 2.7V to 5.5V synchronous buck regulator with HyperLight Load mode. 400mA output current HyperLight Load provides very-high efficiency at light Up to 93% efficiency and 88% at 1mA loads and ultra-fast transient response which is perfectly 21A typical quiescent current suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very-low output 4MHz PWM operation in continuous mode ripple voltage throughout the entire load range with the use Ultra-fast transient response of small output capacitors. The tiny 1.6mm x 1.6mm Thin Low voltage output ripple MLF package saves precious board space and requires 20mVpp ripple in HyperLight Load mode only three external components. 3mV output voltage ripple in full PWM mode The MIC23031 is designed for use with a very-small 0.01A shutdown current inductor, down to 0.47H, and an output capacitor as small as 2.2F that enables a sub-1mm height. Fixed and adjustable output voltage options available The MIC23031 has a very-low quiescent current of 21A 6-pin 1.6mm x 1.6mm Thin MLF and achieves as high as 88% efficiency at 1mA. At higher 40 C to +125 C junction temperature range loads, the MIC23031 provides a constant switching Applications frequency around 4MHz while achieving peak efficiencies up to 93%. Mobile handsets The MIC23031 is available in a 6-pin 1.6mm x 1.6mm Thin Portable media/MP3 players MLF package with an operating junction temperature Portable navigation devices (GPS) range from 40 C to +125C.
