The LTC3851AEMSE-1#TRPBF is a synchronous step-down switching regulator controller manufactured by Analog Devices. It is designed to drive an all N-channel synchronous power MOSFET stage.
Key electrical specifications include a wide input voltage range from 4V to 38V, with an output voltage range of 0.8V to 5.5V. The controller boasts a ±1% output voltage accuracy and a phase-lockable fixed frequency that can operate from 250kHz up to 750kHz. It also features very low dropout operation with a 99% duty cycle and a low shutdown current of 20µA.
This device supports RSENSE or DCR current sensing and includes features like OPTI-LOOP compensation for optimized transient response. The controller is available in thermally enhanced MSOP and 3mm x 3mm QFN packages, suitable for surface mount applications.
