LTC3810 7V to 80V Input Voltage to 5V/5A with IC Power from 12V Supply and All Ceramic Output Capacitors

7V to 80V Input Voltage to 5V/5A with IC Power from 12V Supply and All Ceramic Output Capacitors

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.
