The LTC7810ELXE#PBF from Analog Devices is a dual, 2-phase synchronous step-down DC/DC controller designed for high-performance applications. It drives N-channel synchronous power MOSFETs and can operate from input voltages ranging from 4.5V to 140V, with an absolute maximum rating of 150V.
This controller features a constant frequency current mode architecture, allowing for a phase-lockable frequency up to 720kHz and a programmable fixed frequency from 50kHz to 750kHz. The output voltage can be programmed from 1V to 60V, and the gate drive voltage is adjustable up to 10V to accommodate different FET types and maximize efficiency. The device also includes optional spread spectrum operation to reduce EMI.
Key features include low operating quiescent current of 16μA, very low dropout operation with 100% duty cycle, and selectable operation modes (Continuous, Pulse-Skipping, or Low Ripple Burst Mode) for light loads. It supports RSENSE or Inductor DCR current sensing and offers programmable input overvoltage lockout.
The LTC7810ELXE#PBF is supplied in a 48-lead eLQFP package suitable for surface mounting. It is AEC-Q100 qualified for automotive applications, making it suitable for automotive, industrial, telecommunications, and military/avionics systems.
