LTC3810IG#PBF

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. This uses a constant on-time valley current control architecture to deliver very low-duty cycles with accurate cycle-by-cycle current limits, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides a very fast line and load transient response. Application includes 48V telecom and base station power supplies, networking equipment, serves, automotive and industrial control systems.

• No current sense resistor required
