Description
General part information
MIC23254 Series
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%.
