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 RDS(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.
