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 2.5 mm x 2.0 mm HJDFN package saves precious board space and requires only two external capacitors. The MIC33030 is designed for use with tiny output capacitors as small as 2.2 µF. 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 78% at 1 mA, with a very low quiescent current of 21 µA. At higher loads, the MIC33030 provides a constant switching frequency up to 8 MHz. The MIC33030 is available in a 10-lead 2.5 mm x 2.0 mm HJDFN package with an operating junction temperature range of –40°C to +125°C. 8 MHz 400 mA Internal Inductor Buck Regulator with HyperLight Load® |
