MIC23031-AYMT-TR Power Management ICs - PMIC by Microchip Technology
4MHz 400mA HyperLight Load® Synchronous Buck Regulator
| Status: | Active |
|---|---|
| Series: | MIC23031 |
| RoHS: | Compliant |
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 capacitors.
The MIC23031 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2 µF that enables a sub-1mm height.
The MIC23031 has a very low quiescent current of 21µA and achieves as high as 88% efficiency at 1mA. At higher loads, the MIC23031 provides a constant switching frequency around 4MHz while achieving peak efficiencies up to 93%.
