LTC3827EUH

The LTC3827EUH by Linear Technology is a dual, 2-phase synchronous step-down controller designed for efficient power management. It features a wide input voltage range from 4V to 36V and can regulate output voltages between 0.8V and 10V. The controller offers a low operating quiescent current of 80μA (one channel on) and a low shutdown current of 8μA. It supports selectable continuous, pulse skipping, or low ripple Burst Mode operation at light loads. The device includes dual N-channel MOSFET synchronous drive and very low dropout operation with a 99% duty cycle capability.

Key electrical specifications include a fixed frequency operation from 140kHz to 650kHz, ±1% output voltage accuracy, and the ability to deliver up to 25A of output current. The LTC3827EUH also provides features such as adjustable output voltage, soft-start or tracking, output current foldback limiting, power good output voltage monitor, and output overvoltage protection.

Packaged in a compact 5mm x 5mm QFN-32 package, this controller is suitable for surface mount applications. Its operating temperature range is from 0°C to 85°C. The out-of-phase controllers help reduce required input capacitance and power supply induced noise, making it a robust solution for various applications.
