The SA23002C high-efficiency synchronous Buck converter can deliver 2A output current over an input voltage range from 2.8V to 5.5V. It uses built-in power MOSFETs to supply a resistor-configurable output voltage between 0.6V and VIN. The fixed 2.35MHz switching frequency allows for small external inductor and capacitor values.

The SA23002C is available in a DFN2mmx2mm-8 package.
