Overview
The CL25N3-G is a high-voltage, linear constant-current LED driver IC manufactured by Microchip Technology. Designed for single-output applications, it delivers a fixed output current of 25 mA with an external MOSFET configuration. The device supports a wide input voltage range from 5 V to 90 V and can drive loads up to 590 V output voltage. It operates reliably within a temperature range of -40°C to +125°C and is housed in a TO-92-3 through-hole package.
Feature Summary
- Provides stable constant current regulation for LED lighting applications
- Supports wide input voltage operation suitable for various power sources
- Features temperature compensation to maintain consistent performance across operating conditions
Applications
- LED lighting drivers
- Constant current source circuits
- High voltage LED arrays
Procurement Notes
Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and production batch.
Selection Notes
Select this component when a simple, cost-effective solution for driving LEDs at a fixed 25 mA current is required. It is suitable for designs needing high voltage tolerance without complex switching topology. Ensure the thermal management strategy accounts for the linear regulation nature of the device under maximum load conditions.
Part Context
This part belongs to Microchip's CL series of LED driver ICs, which are specialized for providing regulated current to light-emitting diodes. The series focuses on simplicity and reliability for general illumination tasks, offering a robust alternative to more complex PWM dimming controllers in basic lighting fixtures.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as the CL2N3-G, which offers a similar form factor but with a different nominal current rating. Verify that any substitute maintains the required output voltage headroom and thermal characteristics.
