Introduction
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. The 4mm x 4mm QFN package saves board space and requires only five external components for each channel. The MIC23451 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 that is less than 1mm height. The MIC23451 has a very-low quiescent current of 24μA each channel and achieves as high as 81% efficiency at 1mA. At higher loads, the MIC23451 provides a constant switching frequency around 3MHz while achieving peak efficiencies up to 93%. The MIC23451 is available in a 26-pin 4mm x 4mm QFN package with an operating junction temperature range from -40°C to +125°C.
