MIC23603
4 MHz PWM 6A Buck Regulator with HyperLight LoadВ®
Features General Description The MIC23603 is a high-efficiency 4 MHz 6A
synchronous buck regulator with HyperLight LoadВ®
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 4 mm x 5 mm DFN package saves precious board
space and requires few external components. Input Voltage: 2.7V to 5.5V
