LTC1435IG#TRPBF

DC DC Switching Controllers Overview

The LTC1435IG#TRPBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5 V to 36 V and provides an adjustable output voltage from 1.19 V to 9 V. The device supports an output current of 15 A at a fixed switching frequency of 125 kHz. It features low operating supply current, typically 260 µA, and includes shutdown functionality. Packaged in a 16-lead SSOP, it is designed for high-efficiency power conversion applications.

DC DC Switching Controllers Feature Summary

• Synchronous buck controller architecture driving external N-channel MOSFETs
• Fixed frequency operation ensuring stable noise performance
• Integrated shutdown pin for power management efficiency

DC DC Switching Controllers Applications

• Point-of-load DC-DC conversion modules
• Industrial control system power supplies
• Telecommunications equipment backend power distribution

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. or its authorized licensee LT. Ensure the component matches the 16-SSOP package dimensions. Check RoHS compliance status as required by your assembly specifications. Validate that the part number corresponds to the active lifecycle stage for long-term availability.

DC DC Switching Controllers Selection Notes

Select this controller when designing a synchronous buck converter requiring external MOSFETs for higher current handling than integrated solutions offer. The fixed 125 kHz frequency allows for optimized inductor selection. Consider the 3.5 V minimum input voltage constraint against your source rail. The 15 A capability depends on external component thermal design. Use the shutdown feature for system-level power sequencing requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC1435 family of synchronous step-down switching regulators. It is distinct from the LTC1435A variant which may have different electrical characteristics. The IG suffix denotes the industrial temperature range and SSOP package. It serves as a controller rather than a complete monolithic regulator, requiring external power stages.

DC DC Switching Controllers Replacement Considerations

The LTC1435AIS#TRPBF is a related variant within the same family. Verify if the specific electrical tolerances or temperature ranges of the AIS version meet your design requirements before substitution.
