The SY2A23003A high-efficiency synchronous Buck converter can deliver 3A 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 SY2A23003A is available in a DFN1.4mm× 1.8mm-6 package.
