LTC3834EDHC-1#TRPBF

DC DC Switching Controllers Overview

The LTC3834EDHC-1#TRPBF is a synchronous step-down controller from Analog Devices, designed for high-efficiency power conversion. It supports an input voltage range of 4 V to 36 V and delivers up to 25 A output current with an adjustable output voltage between 800 mV and 10 V. The device features a low quiescent current of 4 uA and operates at a fixed switching frequency of 400 kHz. Packaged in a 16-lead DFN (5mm x 3mm) with an exposed pad, it functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the requested package and tape/reel configuration. Review the latest datasheet for any engineering change notices that may affect pinout or electrical characteristics before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring high current capability with minimal quiescent loss. Ensure the external MOSFETs are rated for the expected current and voltage stresses. Verify that the required output voltage falls within the specified 800 mV to 10 V range and that the operating environment stays within the -40°C to +85°C thermal limits.

DC DC Switching Controllers Part Context

This part belongs to the LTC3834 family of synchronous step-down controllers. It shares functional similarities with other members like the LTC3834EGN-1#PBF but differs in packaging and reel specifications. The EDHC-1 variant specifically utilizes a 16-lead DFN package optimized for surface-mount assembly in compact designs.

DC DC Switching Controllers Replacement Considerations

The LTC3834EGN-1#PBF serves as a direct alternative with identical electrical specifications but uses an SSOP-16 package instead of the DFN form factor. Ensure mechanical clearance and thermal dissipation requirements align with the chosen package type during substitution planning.
