LTC3785EUF-1#TRPBF

DC DC Switching Controllers Overview

The LTC3785EUF-1#TRPBF is a synchronous buck-boost DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7V to 10V and supports adjustable output voltages. The device features a 24-WFQFN package with exposed pad for surface mount installation. It includes integrated synchronous rectification, current limit protection, enable control, and soft-start functionality. The operating temperature range extends from -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Synchronous buck-boost topology drives all N-channel power MOSFETs regardless of input voltage relative to output
• Integrated synchronous rectification for high efficiency across wide input-output differential ranges
• Built-in current limit, enable, and soft-start control characteristics for stable operation

DC DC Switching Controllers Applications

• Battery-powered systems requiring regulation above, below, or equal to battery voltage
• High-efficiency DC-to-DC conversion in portable electronics
• Power management in industrial equipment with varying supply conditions

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EUFD versus EUHF if pinout compatibility is critical, as package dimensions may differ. Confirm RoHS compliance status through official datasheets prior to integration. Ensure ESD handling procedures are followed during assembly due to the exposed thermal pad design. Cross-reference the exact part number with manufacturer documentation to avoid substitution errors.

DC DC Switching Controllers Selection Notes

Select this component when input voltage fluctuates around the required output level, eliminating the need for separate boost or buck stages. The synchronous design reduces external component count compared to non-synchronous alternatives. Evaluate thermal performance requirements based on the 24-QFN package's heat dissipation capabilities under maximum load conditions.

DC DC Switching Controllers Part Context

This controller belongs to the LTC3785 family of high-power synchronous buck-boost controllers. It is designed to replace discrete solutions in applications where input voltage varies significantly relative to the output. The device simplifies design by integrating gate drivers for both high-side and low-side N-channel MOSFETs.

DC DC Switching Controllers Replacement Considerations

LTC3785EUFD#PBF is a tube-packaged equivalent of the same electrical specification. LTC3789 series devices offer similar buck-boost functionality but may require different external component values. Verify pin compatibility before substituting with other Analog Devices buck-boost controllers.
