The LTC3851EGN#TRPBF from Analog Devices is a high-performance synchronous step-down switching regulator controller designed to drive an all N-channel synchronous power MOSFET stage. It features a constant frequency current mode architecture with a phase-lockable frequency range of 250kHz to 750kHz.
This controller supports a wide input supply voltage range from 4V to 38V and provides an adjustable output voltage from 0.8V to 5.5V with ±1% accuracy. The OPTI-LOOP compensation allows for optimized transient response across various output capacitance and ESR values. It includes features such as adjustable soft-start or tracking, output current foldback limiting, and output overvoltage protection.
The LTC3851EGN#TRPBF is available in a 16-SSOP package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA). The device also offers selectable operating modes at light loads, including continuous, pulse-skipping, or Burst Mode operation, and a low shutdown quiescent current of 20μA.
Applications for this regulator controller include automotive systems, telecom systems, industrial equipment, and distributed DC power systems.
