MIC33030
8MHz 400mA Internal Inductor Buck
Regulator with HyperLight Load?
General 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 2.5mm x 2.0mm MLF ? package
saves precious board space and requires only two external
capacitors.
The MIC33030 is designed for use with tiny output
capacitors as small as 2.2μF. 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 78% 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
MLF ? package with an operating junction temperature
range of –40 ° C to +125 ° C.
