LTC3879 Datasheet - Linear Technology Corporation

LTC3879 Wide Operating Range No RSENSE Step-Down Controller

The LTC®3879 is a synchronous step-down switching regulator controller optimized for high switching frequency and fast transient response. The constant on-time valley current mode architecture allows for a wide input range, including very low duty factor operation. No external sense resistor or slop.
