LT3582EUD#TRPBF

Overview

The LT3582EUD#TRPBF is an I2C programmable boost and single inductor inverting DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2.475 V to 5.5 V, delivering a fixed 12 V output at up to 200 mA. The device features two outputs with a typical quiescent current of 325 uA and a switching frequency of 100 kHz. Packaged in a 16-lead QFN, it supports operation from -40°C to +125°C.

Feature Summary

• Integrates I2C programmability for flexible configuration
• Utilizes a single inductor architecture for dual output generation
• Supports both boost and inverting topologies

Applications

• Portable electronic devices requiring multiple supply rails
• Battery-powered systems needing efficient voltage conversion
• Industrial control modules with space constraints

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the E-grade temperature rating matches environmental requirements. Check for obsolescence notices as availability may be limited. Ensure compatibility with existing I2C bus protocols during integration.

Selection Notes

Select this component when a compact solution for generating positive and negative voltages from a low-voltage source is required. The I2C interface allows dynamic adjustment capabilities not available in fixed regulators. Consider the 16-QFN package size against board space limitations and thermal dissipation needs.

Part Context

This part belongs to the LT3582 series of power management ICs designed for high-efficiency conversion in small form factors. It complements other Analog Devices regulators by offering combined boost and inversion functions in a single package, reducing component count compared to discrete solutions.

Replacement Considerations

LT3582EUD#PBF is the tube-packaged equivalent of this part number.
