2-A, Low Profile MicroSiP™ Power Module
MicroSiP™ module optimized for small solution size
DCS-Control™ Topology
and high efficiency. The power module integrates a
Up to 95% Efficiency
synchronous step-down converter and an inductor to
simplify design, reduce external components and

surface mount equipment.
2.5-V to 6-V Input Voltage Range
To maximize efficiency, the converter operates in
0.8-V to VIN Adjustable Output Voltage
PWM mode with a nominal switching frequency of
2.4MHz and automatically enters Power Save Mode
