NCL30486A1DR2G

Overview

The NCL30486A1DR2G is a smart-dimmable constant current/constant voltage (CC/CV) primary side regulation (PSR) controller designed for LED lighting applications. It operates in flyback topology with an input voltage range of 10.2 V to 26.5 V and a fixed switching frequency of 65 kHz. The device features brown-out protection at 138 VDC and supports adjustable output voltage. It is housed in a SOIC-9 package, rated for operation between -40°C and +125°C, with a maximum supply current of 1.88 mA.

Feature Summary

• Supports smart dimming capabilities for LED control
• Integrates constant current and constant voltage regulation modes
• Utilizes primary side regulation for simplified design
• Includes built-in brown-out protection

Applications

• LED lighting drivers
• Smart dimmable lighting systems

Procurement Notes

Verify component authenticity through authorized onsemi channels or certified distributors. Confirm the specific suffix 'A1' matches project requirements as variants exist within the series. Check datasheet revisions for updated electrical characteristics. Ensure compliance with RoHS directives if required by the application. Validate that the SOIC-9 package footprint aligns with PCB layout specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated CC/CV regulation without secondary side feedback components. Consider the 65 kHz switching frequency for magnetic component sizing. Evaluate the 10.2 V to 26.5 V supply range against available power rails. Compare thermal performance in SOIC-9 packaging against higher power alternatives if heat dissipation is a constraint. Verify compatibility with required dimming protocols supported by the controller.

Part Context

This part belongs to the NCL30486 family of LED driver ICs from onsemi. The family includes variants such as NCL30486B1DR2G, which may differ in output current ratings or specific dimming features. These controllers are positioned for high-efficiency offline LED applications using flyback converters. The A1 suffix denotes specific electrical parameters distinct from other series members.

Replacement Considerations

NCL30486B1DR2G is a related variant within the same product family. Verify pinout compatibility and specific parameter differences such as output current limits before substitution. Consult official documentation for detailed comparison of electrical characteristics between the A1 and B1 suffixes.
