The LTC3891EFE#TRPBF from LT is a high-performance, synchronous step-down switching regulator DC/DC controller. It drives an all N-channel synchronous power MOSFET stage and operates with a constant frequency current mode architecture, allowing for a phase-lockable frequency up to 750kHz.
This controller boasts a wide 4V to 60V input supply range, making it suitable for various intermediate bus voltages and battery chemistries. The output voltage can be programmed between 0.8V and 24V. Key features include a low operating quiescent current of 50μA, extending run time in battery-powered systems, and a low shutdown current of less than 14μA.
The LTC3891 offers selectable operating modes, including Burst Mode, pulse-skipping, or continuous conduction mode at light loads. It also features OPTI-LOOP compensation for optimized transient response, a precision 0.8V reference, and a power good output indicator. The device supports adjustable output voltage soft-start or tracking and includes output overvoltage protection. It is available in small 20-pin 3mm x 4mm QFN and TSSOP packages.
