The LTC3854EMSE#TRPBF from Analog Devices is a high-performance synchronous step-down DC/DC controller. It is designed to drive an all N-channel synchronous power MOSFET stage.
This controller operates with a wide input voltage range from 4.5V to 38V, allowing for flexible power supply designs. It regulates output voltages from 0.8V to 5.5V. The device features a constant frequency current mode architecture operating at 400kHz, with a minimum on-time of 75ns, making it suitable for high step-down ratio applications. The onboard MOSFET drivers can support external MOSFETs for output currents up to 20A.
Key features include RSENSE or DCR current sensing, ±1% reference voltage accuracy over temperature, and very low dropout operation with up to 97% duty cycle. It also includes adjustable output voltage soft-start and output current foldback limiting for protection during short-circuit conditions. The LTC3854EMSE#TRPBF is available in tiny thermally enhanced 12-pin DFN and MSOP packages, suitable for surface mount applications.
Applications for this controller include automotive systems, telecom systems, industrial equipment, and distributed DC power systems.
