LT3580EDD#PBF

Overview

The LT3580EDD#PBF is a monolithic switching regulator featuring an integrated 2A power switch, designed for boost and inverting DC/DC converter topologies. It operates with an input voltage range of 2.5V to 32V and delivers up to 42V output. The device supports adjustable switching frequencies from 200kHz to 2.5MHz and includes soft-start functionality. Packaged in an 8-lead DFN (3x3mm) with exposed pad, it functions within a temperature range of -40°C to +125°C junction temperature.

Feature Summary

Integrates a high-current 2A power switch for efficient power conversion
Supports flexible boost and inverting regulator configurations
Features programmable switching frequency synchronization capability
Includes built-in soft-start to limit inrush current during startup

Applications

Converting 5V to 12V sources to generate negative voltages such as -12V
High-efficiency boost converter designs operating at 1.2MHz
Flyback power supply applications requiring compact transformer solutions
General-purpose positive or negative voltage regulation from single supplies

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with required thermal management strategies due to the exposed pad design. Confirm that the selected variant meets all environmental and regulatory standards for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring both boost and inverting capabilities within a single IC. Consider the 2A switch current limit and the wide input voltage range suitable for battery-powered or varying source applications. Evaluate the need for external synchronization if noise immunity is critical, and ensure adequate thermal relief on the PCB for the DFN package.

Part Context

This part belongs to the LT3580 series of switching regulators manufactured by Analog Devices Inc. The series is characterized by its versatility in handling multiple converter topologies using a single chip architecture. It is categorized under Power Management ICs (PMIC) specifically within the DC-DC switching regulator subcategory, targeting applications needing compact and efficient power solutions.
