General Description

The MIC23451 is a high-efficiency, 3MHz, triple 2A, ® synchronous buck regulator with HyperLight Load mode.

HyperLight Load provides very-high efficiency at light loads and ultra-fast transient response, which is ideal 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.

Overview
