MIC23603
4MHz PWM 6A Buck Regulator with HyperLight Load® Revision 1.1
General Description
The MIC23603 is a high-efficiency 4MHz 6A synchronous ® buck regulator with HyperLight Load mode. HyperLight Load provides very high efficiency at light loads and ultrafast 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 4mm x 5mm DFN package saves precious board space and requires few external components. The MIC23603 is designed for use with a very small inductor, down to 0.33µH, and an output capacitor as small as 47µF that enables a sub-1mm height.
