LTC3879 Datasheet (Linear Technology Corporation) - Wide Operating Range No RSENSE Step-Down Controller

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
