LTC1649CS#TRPBF

DC DC Switching Controllers Overview

The LTC1649CS#TRPBF is a high-power step-down switching regulator controller from Analog Devices Inc., designed for applications requiring a fixed 3.3V input. It operates at a switching frequency of 200 kHz and supports output voltages ranging from 1.26 V to 2.5 V with an output current capability of 10 A. The device is housed in a 16-lead SOIC package (Narrow 0.15 Inch) and functions within a commercial temperature range of 0°C to 70°C. It is supplied in a reel packaging format with a quantity of 2500 units per reel.

DC DC Switching Controllers Feature Summary

• Integrated control circuitry for high-power buck converter topologies
• Fixed 3.3V input voltage requirement for simplified power design
• Programmable output voltage range supporting low-voltage digital loads

DC DC Switching Controllers Applications

• High-power point-of-load regulation systems
• Industrial equipment power distribution networks
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the 16-lead SOIC package dimensions match your PCB footprint requirements. Ensure the 3.3V input constraint aligns with your system's power rail availability before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 3.3V input source is available and high output current up to 10 A is required. The 200 kHz switching frequency offers a balance between efficiency and passive component size. Consider the commercial temperature range limits if operation in extreme environments is necessary.

DC DC Switching Controllers Part Context

This part belongs to the LTC1649 family of switching regulators, specifically optimized for high-power step-down applications. It serves as a core control element in DC-DC conversion stages, distinct from linear regulators or lower-power controllers. The CS variant denotes the commercial temperature grade and SOIC package style.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing gate drivers and inductor specifications if considering alternative controllers from other manufacturers.
