Typical Application
Description
SY21052 develops a high efficiency synchronous step down DC/DC regulator capable of delivering 1.2A continuous, 1.8A peak current. The SY21052 operates over a wide input voltage range from 7V to 85V and integrates a main switch and a synchronous switch with very low RDS(ON) to minimize the conduction loss.
The device adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
