MIC33030中文资料8MHz 400mA Internal Inductor Buck Regulator Power Module w/Hyper Light Load™数据手册Microchip规格书

描述 Description

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. The tiny 2.0mm x 2.5mm package saves precious board space with an integrated inductor and requires only two external capacitors.The MIC33030 is designed for use with miniscule output capacitors as small as 2.2µF. This gives the MIC33030 the ease of use of an LDO with the efficiency of a HyperLight Load® DC converter.The MIC33030 achieves efficiency in HyperLight Load® mode as high as 75% at 1mA, with a very-low quiescent current of 21µA. At higher loads, the MIC33030 provides a constant switching frequency up to 8MHz.The MIC33030 is available in a 10-pin 2.5mm x 2.0mm package with an operating junction temperature range of -40°C to +125°C.
