Overview
The CL2N3-G is a linear constant current LED driver IC manufactured by Microchip Technology. It features a single output capable of delivering 20 mA with temperature compensation to maintain stable LED brightness across varying thermal conditions. The device operates within an input voltage range of 5 V to 90 V and supports a maximum supply voltage of 90 V. Designed for boost topology applications, it functions reliably in temperatures from -40°C to +125°C. The component is housed in a TO-92-3 package and includes humidity sensitivity considerations.
Feature Summary
- Provides constant current regulation for LED loads
- Includes internal temperature compensation for consistent brightness
- Supports wide input voltage operation up to 90 V
Applications
- LED lighting systems requiring constant current drive
- Industrial illumination with wide voltage inputs
- Temperature-sensitive lighting environments
Procurement Notes
Verify the specific ordering suffix and package variant against the official Microchip datasheet before procurement. Confirm that the TO-92-3 package meets your assembly requirements. Ensure compliance with RoHS directives as indicated in the product specifications. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer to avoid supply chain disruptions during production.
Selection Notes
Select this component when a simple, low-pin-count solution for constant current LED driving is required. It is suitable for designs needing temperature-compensated current regulation without complex external circuitry. Consider the 20 mA output limit and 90 V maximum voltage rating to ensure compatibility with the target LED string configuration and power supply constraints.
Part Context
This part belongs to Microchip's portfolio of LED lighting driver integrated circuits. It is designed for straightforward implementation in lighting applications where stability and minimal external components are prioritized. The device complements other power management solutions by offering dedicated functionality for LED current regulation in compact packages.
Replacement Considerations
Consult the official Microchip documentation for direct pin-to-pin replacements or comparable parts. Verify electrical parameters such as output current and maximum voltage ratings match the original design requirements before substituting.
