MIC33153 - 4MHz PWM 1.2A Internal Inductor Buck Regulator with HyperLight Load ?
4MHz PWM 1.2A Internal Inductor
Buck Regulator with HyperLight Loadâ„¢
and Power Good General Description Features The MIC33153 is a high-efficiency 4MHz 1.2A
synchronous buck regulator with an internal inductor,
HyperLight Loadâ„¢ mode, Power Good (PG) output
indicator, and programmable soft start. HyperLight Loadâ„¢
provides very high efficiency at light loads and ultra-fast
transient response which makes the MIC33153 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 MIC33153 is designed so that only two external
capacitors as small as 2.2ÂµF are needed for stability. This
gives the MIC33153 the ease of use of an LDO with the
efficiency of a HyperLight Loadâ„¢ DC converter. The
MIC33153 achieves efficiency in HyperLight Load mode
as high as 85% at 1mA, with a very low quiescent current
of 22ÂµA. At higher loads, the MIC33153 provides a
constant switching frequency up to 4MHz.
The MIC33153 is available in 14-pin 3.0mm x 3.5mm ...
