Overview
The LT8580IDD#PBF is a DC-DC switching regulator manufactured by Analog Devices Inc., housed in an 8-WFDFN (3x3) package with an exposed pad. It supports Boost, Cuk, and SEPIC topologies with adjustable output voltage ranging from 1.2V to 65V. The device features a maximum switch current of 1.2A and operates within an input voltage range of 2.9V to 40V. Switching frequency is programmable between 200kHz and 1.5MHz. It provides positive or negative output configurations and functions reliably across a junction temperature range of -40°C to 150°C.
Feature Summary
- Supports multiple converter topologies including boost, inverting, and SEPIC configurations for flexible power design.
- Integrated high-voltage switch capable of handling up to 65V drain-source voltage.
- Programmable switching frequency allows optimization for efficiency and external component size.
- Capable of generating both positive and negative output voltages from a single input source.
Applications
- Industrial control systems requiring isolated or non-isolated power rails
- Battery-powered equipment needing extended operating voltage ranges
- Automotive electronics utilizing wide input voltage sources
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm the 8-WFDFN package dimensions match the PCB footprint requirements. Ensure the thermal pad connection is properly designed for heat dissipation given the 150°C junction rating. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.
Selection Notes
Select this component when a single IC must support multiple topology options such as boost or SEPIC. The 1.2A switch current rating suits moderate power applications. Consider the 8-WFDFN package for compact surface-mount designs. Verify that the required output voltage falls within the 1.2V to 65V adjustable range. Check if the operating temperature range meets the environmental conditions of the target application.
Part Context
The LT8580 series includes variants like LT8580IMS8E#PBF and LT8580HDD#TRPBF. These share similar core functionalities but differ in package types such as MSOP-8 or tape-and-reel options. The IDD#PBF variant specifically denotes the DFN package with tube packaging. All variants belong to the same family of multi-topology switching regulators designed for versatile power conversion needs.
Replacement Considerations
LT8580EDD#PBF offers similar specifications in the same DFN package. LT8580HDD#PBF provides enhanced performance characteristics within the identical footprint. LT8580EMS8E#PBF serves as a pin-compatible alternative using the MSOP-8 package. Verify electrical parameters and thermal performance before substituting any of these cross-model variants.
