SQ27692 Datasheet | Silergy

High Efficiency, 60V Input, 2A Asynchronous Step Down Regulator General Description The SQ27692 develops a high efficiency, current mode adaptive constant OFF time controlled, asynchronous step-down DC/DC converter capable of delivering 2A output current. The SQ27692 operates over a wide input voltage range from 4.5V to 60V and integrates main switch with very low RDS(ON) to minimize the conduction loss. The switching frequency is adjustable from 100k Hz to 1MHz using an external resistor. And the device Features cycle-by-cycle peak current limitation.
