The LTC3854IMSE#PBF 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 features a wide operating input voltage range from 4.5V to 38V, with an absolute maximum rating of 40V. It regulates output voltages from 0.8V to 5.5V. The device operates at a constant 400kHz switching frequency and offers a minimum on-time of 75ns, making it suitable for high step-down ratios. The onboard MOSFET drivers can support output currents up to 20A.
The LTC3854IMSE#PBF includes features like adjustable output voltage soft-start, output current foldback limiting (disabled during soft-start), and output overvoltage protection. It also has a 5V LDO for external gate drive and OPTI-LOOP compensation for transient response optimization.
Available in tiny thermally enhanced 12-pin DFN and MSOP packages, this controller is well-suited for applications in automotive systems, telecom systems, industrial equipment, and distributed DC power systems.
