LTC3785EUF

DC DC Switching Controllers Overview

The LTC3785EUF is a synchronous buck-boost DC-to-DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7V to 10V and supports switching frequencies from 100kHz to 1MHz. The device features a maximum duty cycle of 99% and includes current limit, enable, and soft-start control characteristics. It utilizes a 24-WFQFN package with exposed pad, rated for operation between -40°C and 85°C ambient temperature.

DC DC Switching Controllers Feature Summary

• Synchronous rectification capability driving all N-channel power MOSFETs across input voltages above, below, or equal to the output voltage
• Integrated current mode control architecture with programmable soft-start and cycle-by-cycle current limiting
• High efficiency topology designed for buck-boost conversion without requiring sense resistors

DC DC Switching Controllers Applications

• Battery-powered systems requiring stable output during discharge cycles
• Industrial controllers operating with variable supply rails
• Automotive electronics managing fluctuating input voltages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the EUF designation corresponds to the 24-QFN (4x4mm) package variant. Ensure compatibility with RoHS3 standards if environmental compliance is required for the target assembly process.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring wide input voltage ranges relative to the output. The synchronous buck-boost topology eliminates the need for external Schottky diodes. Verify that the 2.7V minimum Vcc requirement aligns with the system's available rail before implementation.

DC DC Switching Controllers Part Context

This part belongs to the LTC3785 family of high-power synchronous buck-boost controllers. It shares functional similarities with the LTC3785-1 but lacks the integrated Power Good indicator found in the derivative model. The series is designed for applications demanding high efficiency across varying load conditions.

DC DC Switching Controllers Replacement Considerations

LTC3785EUF#TRPBF serves as the full reel version of this component. Direct pin-compatible alternatives within the same family include the LTC3785-1, though feature sets differ regarding status indicators.
