LTC3810 15V to 80V Input Voltage to 3.3V/5A with Fault Timeout, Pulse Skip and VIN UV Disabled

15V to 80V Input Voltage to 3.3V/5A with Fault Timeout, Pulse Skip and VIN UV Disabled

The LTC3810 is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The LTC3810 uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor.
