LTC3878 Datasheet - Linear Technology Corporation

LTC3878 Wide Operating Range No RSENSE Step-Down Controller

The LTC®3878 is a synchronous step-down switching DC/DC 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 slope co.
