LTC3766EUFD#PBF

Power Supply Controllers, Monitors Overview

The LTC3766EUFD#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc., housed in a 28-lead QFN package. It operates with an input voltage range of 5V to 32V and supports output voltages from 0.6V to 14.7V. The device delivers up to 3A per channel across two independent outputs, utilizing a fixed switching frequency of 4MHz. It features low quiescent current of 500µA and functions within a temperature range of -40°C to +125°C.

Power Supply Controllers, Monitors Feature Summary

• Dual-channel monolithic synchronous buck regulator architecture
• Direct Flux Limit technology for precise current control
• Integrated soft-start and power-good monitoring capabilities

Power Supply Controllers, Monitors Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Portable instrumentation power supplies

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix EUFD against official Analog Devices documentation to confirm the exact package variant and RoHS compliance status. Confirm availability through authorized distributors as supply may be restricted. Ensure the ordering part number matches the required thermal pad configuration for proper PCB mounting.

Power Supply Controllers, Monitors Selection Notes

Select this component when dual isolated or non-isolated low-voltage rails are required from a higher input source. The 4MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load requirements do not exceed the 3A per channel limit and that the input voltage remains within the specified 5V to 32V window.

Power Supply Controllers, Monitors Part Context

This controller belongs to the LTC3766 family, designed for high-efficiency step-down conversion. It integrates gate drivers and control logic for external N-channel MOSFETs. The QFN package provides enhanced thermal performance for compact designs requiring multiple regulated outputs from a single controller.

Power Supply Controllers, Monitors Replacement Considerations

LTC3766EUFD#TRPBF offers identical electrical specifications but utilizes tape-and-reel packaging instead of tube packaging.
