DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'AIS' confirms automotive grade and tape-and-reel packaging. Ensure the 16-pin SOIC footprint matches the design. Confirm RoHS compliance status with the manufacturer. Validate that the 30 V maximum input rating suits the application supply. Check for any specific handling requirements due to the surface mount package type.
DC DC Switching Controllers Selection Notes
Select this controller when automotive reliability is required for buck converter designs. It is suitable for applications needing a fixed 138 kHz switching frequency. The 2 A output capability defines its load limits. Consider external MOSFET selection based on the drive capabilities. Verify thermal performance within the specified operating temperature range.
DC DC Switching Controllers Part Context
This part belongs to the LTC1435A family of synchronous step-down switching regulator controllers. The 'AIS' designation indicates automotive grade qualification and a specific package variant. It shares the core fixed-frequency control architecture with other members of the series but is optimized for automotive environmental standards.
DC DC Switching Controllers Replacement Considerations
LTC1435AI#TRPBF is a non-automotive equivalent. LTC1435AIG#TRPBF is a general-purpose alternative. Verify pin compatibility and electrical specifications before substitution.
