Overview
The LT8582EDKD#TRPBF is a dual-output switching voltage regulator from Analog Devices, featuring Boost, Inverting, and SEPIC topologies. It operates with an input voltage range of 2.5 V to 22 V and supports two independent outputs up to 42 V. The device provides a switch current of 3 A and includes fault protection mechanisms. It functions at a switching frequency of 2.5 MHz with a shutdown feature. The component is housed in a 24-lead DFN package and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple DC/DC converter topologies including boost, inverting, and SEPIC configurations for versatile power management.
- Integrates dual independent output channels capable of delivering regulated power simultaneously.
- Includes built-in fault protection features to enhance system reliability under abnormal conditions.
Applications
- Industrial control systems requiring flexible voltage conversion
- Automotive electronics with wide input voltage ranges
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the lead time and availability status directly with authorized distributors as supply levels may vary. Ensure the 24-DFN package dimensions match your PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual isolated or non-isolated outputs are required from a single input source. Consider the 2.5 MHz switching frequency for balancing efficiency and EMI performance. Evaluate thermal dissipation capabilities given the 3 A switch current rating and ensure adequate heat sinking for the DFN package in enclosed environments.
Part Context
This part belongs to the LT8582 series of high-performance DC/DC converters designed for demanding applications. It complements other Analog Devices power management solutions by offering multi-topology flexibility in a compact form factor. The series targets designs needing robust fault protection and wide operating voltage ranges.
Replacement Considerations
LT8582EDKD#PBF is a tube-packaged alternative with identical electrical specifications. Verify pin compatibility and thermal characteristics when substituting between tape and reel formats. No direct functional replacements are documented; consider similar dual-output controllers if topology changes are acceptable.
