SY21034B
SY21034B is 1.2A Asynchronous Step Down Regulator manufactured by Silergy.
Description
The SY21034B is a high efficiency, current mode adaptive constant OFF time controlled asynchronous step-down DC/DC converter capable of delivering 1.2A output current. The SY21034B operates over a wide input voltage range from 4.5V to 100V and integrates main switch with very low RDS(ON) to minimize the conduction loss.
