Microchip Technology

The MIC23150 is a high-efficiency 4MHz 2A 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 tiny 2mm x 2mm Thin DFN (TDFN) package saves precious board space and requires only three external components. The MIC23150 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2µF that enables a total solution size, less than 1mm height. The MIC23150 has a very low quiescent current of 23µA and achieves a peak efficiency of 93% in continuous conduction mode. In discontinuous conduction mode, the MIC23150 can achieve 87% efficiency at 1mA. The MIC23150 is available in 8-pin 2mm x 2mm Thin DFN package with an operating junction temperature range from -40°C to +125°C.

The MIC23153 is a high efficiency 4MHz 2A synchronous buck regulator with HyperLight Load® mode, Power Good output indicator, and programmable soft-start. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response which makes the MIC23153 perfectly suited for supplying processor core voltage. 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 MIC23153 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 total solution size, less than 1mm in height. The MIC23153 has a very low quiescent current of 22µA and achieves a peak efficiency of 93% in continuous conduction mode. In discontinuous conduction mode, the MIC23153 can achieve 85% efficiency at 1mA.

The MIC23201 is a high efficiency 2MHz 2A synchronous buck regulator with Hyper Speed Control. Hyper Speed Control™ provides 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 MIC23201 is designed for use with a very small inductor, down to 1µH, and an output capacitor as small as 22µF that enables a total solution size, less than 1.5mm height. The MIC23201 provides a constant switching frequency around 2MHz while achieving peak efficiencies up to 90%. Also, checkout MPU power solutions with MIC23201.

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 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 33µA with both outputs enabled and can achieve over 85% efficiency at 1mA. At higher loads the MIC23254 provides a constant switching frequency around 4MHz while providing peak efficiencies over 90%.
