NSV45035JZT1G

Current Regulation/Management Overview

The NSV45035JZT1G is a single-channel LED lighting driver IC from the NSI45035J series, manufactured by onsemi. It operates with a fixed input voltage of 45 V and supports both Boost and Buck topologies. The device provides an adjustable output voltage and delivers a low-level output current of 35 mA, with a maximum output current capability of 70 mA. It functions at a switching frequency of 1 MHz and is housed in a SOT-223 surface-mount package. The component is rated for an operating temperature range from -55°C to +150°C.

Current Regulation/Management Feature Summary

• Provides constant current regulation for LED applications
• Supports flexible Boost and Buck converter topologies
• Features adjustable output voltage control
• Designed for high-temperature operation up to 150°C

Current Regulation/Management Applications

• LED lighting driver circuits
• Constant current regulation for LEDs
• Boost topology LED drivers
• Buck topology LED drivers

Current Regulation/Management Procurement Notes

Verify the specific ordering suffix JZT1G against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required 45 V input voltage and 35 mA target current. Confirm that the SOT-223 footprint matches the PCB design. Check for any recent Product Change Notifications (PCN) or environmental compliance updates prior to finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a fixed 45 V input supply is available and a constant current drive around 35 mA is required. The SOT-223 package suits applications needing robust thermal performance due to its large exposed pad. Consider the 1 MHz switching frequency for inductor size optimization. Verify that the application does not require AEC-Q100 automotive qualification, as this specific part number lacks that certification in the provided data.

Current Regulation/Management Part Context

This part belongs to the NSI45035J family of LED drivers from onsemi. It shares functional similarities with other members like NSI45020JZT1G but differs in output current ratings. The 'J' designation typically indicates specific binning or tolerance characteristics within the series. It is distinct from non-J variants which may have different electrical parameters or packaging options.

Current Regulation/Management Replacement Considerations

NSI45035JZT1G is a direct equivalent part number within the same manufacturer's lineup. NSV45035JZT1G appears to be a variant with identical core specifications but potentially different packaging quantities or regional distribution codes. No cross-manufacturer substitutes are confirmed in the source data.
