SY20277 is a high efficiency 1.5MHz synchronous step down DC/DC regulator capable of delivering up to 12A output currents. It can operate over a wide input voltage range from 2.7V to 5.5V and integrates main switch and synchronous switch with very low R_{DS (ON)} to minimize the conduction loss. The output voltage can be programmed from 0.6V to 1.5V through I²C interface.

SY20277 is in a space saving, low profile QFN3x3-12 package.
