DC DC Switching Controllers datasheet and documents for LTC3873EDDB#TRM

LTC3873EDDB#TRM

DC DC Switching Controllers Overview

The LTC3873EDDB#TRM is a constant frequency current mode DC/DC controller manufactured by Analog Devices Inc. Designed for high input and output voltage applications, this component drives N-channel MOSFETs in boost, flyback, or SEPIC topologies. It operates within an input voltage range of -10V to -15V and provides a regulated -5V output. The device features a fixed switching frequency of 240kHz and supports output currents up to 3A. Packaged in an 8-pin DFN with an exposed pad, it ensures reliable performance across industrial temperature ranges.

DC DC Switching Controllers Feature Summary

Constant frequency current mode control architecture
Capable of driving N-channel MOSFETs for high voltage converters
Supports multiple converter topologies including boost, flyback, and SEPIC

DC DC Switching Controllers Applications

Negative-to-negative (negative buck) converters
Non-isolated telecom housekeeping power supplies
High input and output voltage converter designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package type when ordering, as availability may vary. Confirm that the -10V to -15V input specification aligns with your system requirements. Check for RoHS compliance status and ensure the 8-DFN EP package fits your PCB layout constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring negative voltage conversion from negative inputs. Ensure the external N-channel MOSFETs can handle the required voltage and current ratings. Verify that the 240kHz switching frequency meets EMI and efficiency targets. Consider thermal management solutions due to the exposed pad package design for heat dissipation.

DC DC Switching Controllers Part Context

This component belongs to the LTC3873 family of DC/DC controllers. It shares functional similarities with other members like the LTC3873IDDB-5 but differs in input/output voltage specifications. The EDDB variant specifically targets negative voltage applications, distinguishing it from positive voltage counterparts in the same series.
