Compact Package: SOT563 
 The SY20114 high-efficiency 1.5MHz synchronous step-down DC/DC regulator operates over a wide input voltage range of 2.5V to 5.5V and can deliver an output current up to 2A with a low quiescent current of 55 µA. To minimize conduction loss, it integrates a main switch and a synchronous switch with very low RDS(ON). 
 
The SY20114 is highly integrated, so only the input and output capacitors, inductor, and resistor-divider components need to be selected for the targeted application specifications.
 
The SY20114 is available in a space-saving, low-profile SOT563 package.
