LTC3104EDE#PBF

Overview

The LTC3104EDE#PBF is a high-efficiency, monolithic synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It utilizes a current-mode architecture to deliver up to 300mA of output current with a fixed switching frequency of 1.2MHz. The device supports an input voltage range from 2.5V to 15V and provides an adjustable output voltage between 0.6V and 13.8V. It features a typical quiescent current of 2.6µA in Burst Mode operation and includes an integrated 10mA LDO for low-noise applications. The component is housed in a thermally enhanced 14-lead DFN package (3mm x 4mm x 0.75mm) rated for industrial temperatures from -40°C to 125°C.

Feature Summary

• Integrates a synchronous buck converter with an auxiliary 10mA LDO for noise-sensitive loads
• Offers selectable automatic Burst Mode or forced continuous PWM operation for efficiency and noise optimization
• Features programmable RUN pin threshold for precise power sequencing control
• Includes internal compensation, soft-start, and power-good status indication

Applications

• Remote sensor networks
• Distributed power systems
• Energy harvesting systems
• Portable instrumentation

Procurement Notes

Verify the specific suffix 'EDE' corresponds to the 14-lead DFN package variant when sourcing. Confirm that the '#PBF' designation indicates lead-free RoHS compliance as per manufacturer standards. Ensure the supplier provides original manufacturer documentation to validate authenticity. Cross-reference the full part number against official Analog Devices databases to avoid confusion with similar packages like MSOP.

Selection Notes

Select this component for designs requiring wide input voltage compatibility down to 2.5V. The integrated LDO simplifies board space by eliminating external regulators for sensitive analog circuits. Choose Burst Mode for maximum battery life in light-load scenarios, or forced continuous mode where strict output ripple specifications are mandatory. Verify thermal performance within the DFN enclosure under maximum load conditions.

Part Context

This device belongs to the LTC31xx series of power management ICs designed for energy-efficient applications. It complements other Linear Technology solutions by combining switching regulation with linear stability in a single compact footprint. The family targets portable and remote electronics where size constraints and power conservation are critical design drivers.
