LTC3812-5 Datasheet Synchronous Switching Regulator Controller

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC3812-5 is a synchronous step-down switching regulator controller that can directly step down voltages from up to 60V input, making it ideal for telecom and automotive applications.

The LTC3812-5 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.

A precise internal reference provides 0.5% DC accuracy.
