LTC3780IG#TRPBF

DC DC Switching Controllers Overview

The LTC3780IG#TRPBF is a synchronous four-switch buck-boost 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 switching frequency between 200kHz and 400kHz. It features a low quiescent current of 1.5mA and functions reliably across a temperature range of -40°C to +125°C. Packaged in a 24-SSOP format, it includes integrated soft-start and current limit capabilities for robust power management.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure compatibility with required PCB footprint dimensions. Confirm RoHS compliance status through certified datasheets before integration into final assemblies.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits that require bidirectional voltage conversion from a single rail. Evaluate thermal performance requirements based on the 24-SSOP package constraints. Compare efficiency curves against alternative controllers to ensure optimal system power budget adherence.

DC DC Switching Controllers Part Context

This part belongs to the LTC3780 family of high-efficiency DC/DC controllers. It serves as a specialized solution for applications demanding wide input voltage ranges without external level shifters. The design integrates gate drivers and logic necessary for controlling external N-channel MOSFETs in a compact form factor.

DC DC Switching Controllers Replacement Considerations

LTC3780EG#TRPBF is a documented equivalent offering identical electrical specifications but housed in a 24-SSOP package instead of QFN variants.
