Overview
The LT3684IDD#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts input voltages up to 36V maximum and delivers an output current of 2A. The device features an adjustable switching frequency ranging from 300kHz to 2.8MHz. It provides a positive adjustable output voltage starting at 1.265V with a single output configuration. The operating supply current is specified at 1.2mA. The component is housed in a 10-WFDFN package with an exposed pad.
Feature Summary
- Integrates an adjustable switching frequency capability spanning from 300kHz to 2.8MHz for optimized design flexibility.
- Accepts high input voltages up to 36V maximum, suitable for wide-range power applications.
- Delivers a regulated 2A output current with a minimum adjustable output voltage of 1.265V.
Applications
- Industrial control systems requiring stable step-down conversion
- Distributed power architectures in embedded electronics
- Battery-powered equipment needing efficient voltage regulation
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the part number matches the exact Analog Devices specification sheet for the LT3684 series. Ensure compatibility with the required thermal management solutions due to the DFN package type. Cross-reference the manufacturer's latest documentation to confirm availability status and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a high-input voltage buck converter with adjustable frequency is required. The 2A output current rating suits moderate power loads. Consider the 10-WFDFN package for space-constrained designs. Verify that the external component selection supports the desired switching frequency range between 300kHz and 2.8MHz. Ensure the application environment allows for the thermal dissipation characteristics of the exposed pad package.
Part Context
The LT3684 belongs to Analog Devices' family of synchronous buck regulators designed for efficiency and compactness. This specific model variant includes the IDD suffix indicating the industrial temperature range and the TRPBF suffix denoting reel packaging. It complements other LT368x series devices offering different current capabilities or fixed frequencies within the same architectural framework.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices official resources for direct pin-to-pin replacements or functional equivalents within the LT368x series.
