General Description
The MIC23153 is a high-efficiency 4 MHz 2A
synchronous buck regulator with HyperLight Load®
mode, Power Good (PG) output indicator, and
programmable soft-start. HyperLight Load® provides
very high efficiency at light loads and ultra-fast
transient response that makes the MIC23153 perfectly
suited 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
tiny 2.5 mm x 2.5 mm thin DFN package saves
precious board space and requires only four external
components.
The MIC23153 is designed for use with a very small
inductor, down to 0.47 µH, and an output capacitor as
small as 2.2 µF that enables a total solution size, less
than 1 mm in height.
The MIC23153 has a very-low quiescent current of
22 µA and achieves a peak efficiency of 93% in
continuous conduction mode. In discontinuous
conduction mode, the MIC23153 can achieve 85%
efficiency at 1 mA.
The MIC23153 is available in 10-pin 2.5 mm x 2.5 mm
TDFN package with an operating junction temperature
range from –40°C to +125°C.
