LTC3727LXEUH-1#TRPBF

DC DC Switching Controllers Overview

The LTC3727LXEUH-1#TRPBF is a high-efficiency, dual-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It drives all N-channel synchronous power MOSFET stages for robust power delivery. The device operates with an input voltage range of 2.8V to 36V and supports output voltages from 800mV to 14V. It delivers up to 25A of output current across two channels. The fixed switching frequency is 550kHz, and it functions within a temperature range of -40°C to +85°C. The component is housed in a 32-pin QFN (5x5mm) package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout design.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high efficiency at moderate to high currents where external MOSFETs are preferred for thermal management. Compare against the standard LTC3727 if lower input voltage ranges suffice, as the 'L' variant typically supports wider input ranges. Evaluate the 550kHz switching frequency against EMI constraints and inductor size requirements for the target application.

DC DC Switching Controllers Part Context

This component belongs to the LTC3727 family of dual synchronous step-down regulators. It shares functional similarities with the LTC3727A-1 but differs in specific electrical characteristics and input voltage capabilities. The DC457B evaluation board is designed specifically for the LTC3727A-1 variant, not this specific model, so schematic verification is required before hardware development.

DC DC Switching Controllers Replacement Considerations

The LTC3727EUH-1#TR is a related variant in the same series. Verify pin compatibility and electrical parameter alignment, particularly regarding input voltage limits and switching frequency, before substituting.
