LTC3872IDDB-1#TRMPBF

DC DC Switching Controllers Overview

The LTC3872IDDB-1#TRMPBF is a constant frequency current mode boost DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and utilizes a DFN-8 package for surface mount installation. The device features no external sense resistor current sensing, enabling high efficiency designs. It supports switching frequencies up to 550kHz and includes integrated soft-start and current limit protection functions.

DC DC Switching Controllers Feature Summary

• No RSENSE current mode control architecture eliminates external sense resistors
• Integrated soft-start functionality limits inrush current during startup
• Constant frequency operation simplifies filter design and EMI management

DC DC Switching Controllers Applications

• Single-output boost converter designs
• Non-isolated DC/DC power supply systems
• Battery-powered portable electronics requiring step-up conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging with minimum quantity requirements. Confirm the I-grade temperature rating matches application thermal constraints. Check RoHS compliance status against regional regulatory standards before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing boost converters requiring simplified current sensing without external resistors. Ensure the input voltage range of 2.75V to 9.8V aligns with source availability. Consider the DFN-8 package size for PCB layout constraints and thermal dissipation requirements in compact applications.

DC DC Switching Controllers Part Context

This part belongs to the LTC3872 family of boost controllers designed for high-efficiency power conversion. It shares architectural similarities with other members like the LTC3872ETS8 but differs in package type and temperature grade. The IDDB variant specifically denotes industrial temperature range performance in a small footprint DFN package.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other LTC3872 variants such as LTC3872ETS8#TRPBF for different packaging needs. Verify pin compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure equivalent current sensing and protection features.
