LT3473EDD#TRPBF

Overview

The LT3473EDD#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 4.2V and provides a fixed output voltage of 25V at up to 80mA. The device features an integrated Schottky diode and output disconnect circuitry, housed in a compact 10-lead DFN package.

Feature Summary

• Integrates a Schottky diode for efficient power conversion
• Includes output disconnect circuitry for load management
• Designed for micropower applications requiring high step-up ratios

Applications

• Lithium-ion battery powered systems
• High voltage bias generation from low voltage sources
• Portable electronic devices requiring isolated power rails

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the 10-DFN package type matches your PCB footprint requirements. Ensure the 3V to 4.2V input range aligns with your source voltage characteristics before finalizing procurement.

Selection Notes

Select this component when a fixed 25V output is required from a single-cell lithium battery. The integrated Schottky diode simplifies the design by reducing external component count. Consider the 80mA current limit to ensure it meets the load requirements of your application without exceeding the device's capabilities.

Part Context

This part belongs to the LT3473 series of micropower boost converters. It is distinct from other regulators in the portfolio by its specific focus on generating high voltages from low-voltage inputs using an integrated diode solution. The DFN package allows for space-constrained designs typical in mobile electronics.

Replacement Considerations
