The SY20235 is a high efficiency ultra low quiescent current, 2.0MHz synchronous step-down DC/DC regulator capable of delivering up to 5A output current.
The SY20235 operates over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.
