CL2N3-G-P002

Overview

The CL2N3-G-P002 is a high-voltage, temperature-compensated constant-current LED driver IC manufactured by Microchip Technology. Designed for robust lighting applications, it delivers a precise output current of 20 mA with ±10% trimming accuracy. The device operates within a supply voltage range of 5 V to 90 V and supports an output voltage up to 90 V. It features a TO-92-3 through-hole package suitable for bulk or cut-tape procurement. The component functions reliably across an extended industrial temperature range from -40°C to +125°C, ensuring stable performance in demanding environments without requiring external compensation components.

Feature Summary

• Provides high-voltage constant-current regulation optimized for white LED strings
• Integrated temperature compensation maintains consistent light output across operating conditions
• Factory-trimmed current source ensures precise 20 mA output with minimal tolerance variation

Applications

• Automotive exterior lighting systems
• Industrial high-bay LED fixtures
• Signage and display backlighting

Procurement Notes

Verify the specific suffix P002 indicates the reel packaging format when ordering. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure the TO-92-3 lead configuration matches the target PCB footprint design. Cross-reference the datasheet revision date to confirm the latest electrical characteristics are applied to the production batch.

Selection Notes

Select this component when a simple, single-output linear regulator topology is sufficient for the application. It is appropriate for designs where board space is limited and through-hole mounting is preferred. Consider the 90 V maximum output voltage limit when sizing the LED string. This part eliminates the need for external temperature sensing circuits due to internal compensation mechanisms.

Part Context

The CL2 series represents Microchip's portfolio of dedicated LED drivers focusing on simplicity and reliability. The CL2N3 variant specifically targets automotive and industrial sectors requiring high-voltage operation. The P002 suffix denotes the specific tape-and-reel packaging option, distinguishing it from bulk or other container types available for the same electronic core.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific model.
