The LTC3851AEMSE from Linear Technology (LT) is a high-performance synchronous step-down switching regulator controller. Designed for versatile power management applications, it accepts a wide input voltage range from 4V to 38V.
This controller features a phase-lockable fixed frequency operation, adjustable from 250kHz to 750kHz, with a nominal frequency of 750kHz. It supports dual N-channel MOSFET synchronous drive and offers very low dropout operation with a 99% duty cycle. The output voltage accuracy is ±1%, and it can deliver up to 25A of output current.
Key features include R SENSE or DCR current sensing, a Power Good output voltage monitor, adjustable output voltage with soft-start or tracking, and output current foldback limiting. It also includes output overvoltage protection and OPTI-LOOP compensation to minimize output capacitance. For light loads, selectable continuous, pulse-skipping, or Burst Mode operation is available. The device has a low shutdown current of 20µA.
The LTC3851AEMSE is housed in an MS-16E package. Its operating temperature range is from 0°C to 85°C. This controller is suitable for applications requiring efficient and stable power conversion.
