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 ? 21?A 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 ? 0.01?A shutdown current inductor, down to 0.47?H, and an output capacitor as small as 2.2?F that enables a sub-1mm height. ? Fixed and adjustable output voltage options available ? The MIC23031 has a very-low quiescent current of 21?A ? 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%. ?

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 ? 21?A 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 ? 0.01?A shutdown current inductor, down to 0.47?H, and an output capacitor as small as 2.2?F that enables a sub-1mm height. ? Fixed and adjustable output voltage options available ? The MIC23031 has a very-low quiescent current of 21?A ? 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 +125?C. ? WiFi/WiMax/WiBro modules Data sheets and support documentation can be found on ?
