LT1071HVCKV is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC REG LINEAR SWITCHING REG. Review the specifications below when checking this part for your BOM.
The LT1071HVCKV is a high-voltage switching regulator IC manufactured by Texas Instruments. It operates with supply voltages ranging from 3 V to 60 V, distinguishing it as the high-voltage variant of the LT1071 family. The device supports multiple converter topologies including step-down (buck), step-up (boost), Cuk, flyback, and forward configurations. It features an adjustable output voltage starting at 1.25 V and provides up to 2.5 A of switch current capability. The component is housed in a plastic SFM-5 package.
Verify the specific suffix 'CKV' against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure compatibility with existing PCB footprints for the SFM-5 package. Cross-reference ordering information with authorized distributors to confirm current availability and authenticity before finalizing procurement decisions.
Select this component when input voltages exceed standard 40 V limits but remain within the 60 V maximum rating. Consider the requirement for multiple topology support if design flexibility is needed. Evaluate thermal management requirements given the through-hole packaging and potential current loads. Compare against lower voltage variants if input sources are strictly limited to 40 V or less.
This part belongs to the LT1071 series of switching regulators. The LT1071HV variant specifically extends the input voltage range compared to the standard LT1071. It serves as a foundational power management solution for designs requiring robust voltage conversion capabilities across various industrial and commercial applications.
LT1071HVIT#PBF is a documented substitute offering similar high-voltage performance in a TO-220-5 package.
