DC DC Switching Controllers datasheet and documents for LTC3872EDDB-1#TRMPBF

LTC3872EDDB-1#TRMPBF

DC DC Switching Controllers Overview

The LTC3872EDDB-1#TRMPBF is a No RSENSE current mode boost DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.75V to 9.8V and features a fixed switching frequency of 550kHz. The device utilizes a DFN-8 (3x2) package and includes integrated soft-start functionality. It is designed for applications requiring high efficiency without external current sensing resistors.

DC DC Switching Controllers Feature Summary

Eliminates the need for external current sense resistors through proprietary No RSENSE technology
Provides constant frequency current mode control for stable regulation
Integrates soft-start capability to limit inrush current during startup

DC DC Switching Controllers Applications

Battery-powered portable electronics
Industrial control systems
Telecommunications equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix -1 indicates the correct variant configuration against official Analog Devices documentation. Confirm the DFN-8 package marking and lot date codes match your quality requirements. Ensure compatibility with your PCB footprint design before finalizing orders.

DC DC Switching Controllers Selection Notes

Select this component when designing boost converters that require simplified bill of materials by removing current sense resistors. It is suitable for low-voltage input applications up to 9.8V where moderate output currents are needed. Consider the 550kHz frequency for balancing component size and efficiency.

DC DC Switching Controllers Part Context

This part belongs to the LTC3872 family of No RSENSE controllers from Analog Devices. It is distinct from synchronous buck controllers like the LTC3772 or multi-topology variants like the LTC3873. The EDDB-1 designation specifies the temperature grade and packaging format within the broader product line.
