SY20257P is a high efficiency 2.4MHz synchronous step down DC/DC regulator capable of delivering up to 6A output currents. It can operate over a wide input voltage range from 2.6V 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 1.3875V through I²C interface.

SY20257P is in a space saving, low profile CSP1.56×1.96-20 package.
