Microchip MIC33030-AYHJ-TR, 1 Buck Boost Switching, Buck/Boost Converter 400mA, 0.7 V → 3.6 V, 8 (Typ.) MHz

The MIC33030 is a high-efficiency, 8MHz, 400mA synchronous buck regulator with an internal inductor and HyperLight Load® mode. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response that is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is the very low output ripple voltage throughout the entire load range with the use of small output capacitors.
