LTC3851A-1 Overview
The LTC®3851A-1 is a high performance synchronous step-down switching regulator controller that drives an all N-channel synchronous power MOSFET stage. A constant frequency current mode architecture allows a phase‑lockable frequency of up to 750kHz. OPTI-LOOP pensation allows the transient response to be optimized over a wide range of output capacitance and ESR values.
