LTC3780EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3780EUH#TRPBF is a high-efficiency, synchronous four-switch buck-boost switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports output voltages from 800mV to 30V. The device delivers up to 10A of output current with a single output configuration. Key electrical parameters include a switch frequency ranging from 200kHz to 400kHz, a maximum duty cycle of 99%, and a static current of 1.5mA. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 32-WFQFN package.

DC DC Switching Controllers Feature Summary

• Synchronous four-switch topology enables efficient buck and boost operation across varying input and output voltage conditions.
• Integrated control features include current limit, enable, power good indication, and soft-start functionality.
• Supports external synchronization or adjustable switching frequencies between 200kHz and 400kHz for noise management.

DC DC Switching Controllers Applications

• Battery-powered systems requiring stable output despite fluctuating battery levels
• Industrial equipment needing wide input voltage tolerance
• Automotive electronics utilizing non-isolated DC/DC conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging and lead-free compliance when ordering. Ensure the supplier source matches Analog Devices Inc. specifications. Confirm that the 32-QFN package variant aligns with your PCB footprint requirements before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a single controller must handle both step-down and step-up scenarios without external logic complexity. Consider the 32-WFQFN package for compact designs. Evaluate thermal performance at the target load current, as the controller drives external MOSFETs rather than integrating them directly.

DC DC Switching Controllers Part Context

This part belongs to the LTC3780 family of power management ICs designed for flexible DC/DC applications. It serves as a controller rather than a complete integrated converter, requiring external power switches. The EUH suffix denotes the 32-lead QFN package option within this product line.

DC DC Switching Controllers Replacement Considerations

LTC3780IUH#TRPBF offers the same functional topology but supports an extended industrial temperature range up to 125°C junction temperature. Verify thermal requirements before substituting, as the EUH variant is rated for -40°C to +85°C.
