NCL30488A4DR2G

Overview

The NCL30488A4DR2G is a single-stage constant current/constant voltage (CC/CV) primary side regulation (PSR) controller designed for offline LED lighting applications. It integrates a 108 VDC brown-out detector and supports a soft-start resistor (SSR) option. The device operates in a flyback topology with analog dimming capability, delivering up to 500 mA output current. Packaged in a 7-SOIC format, it provides efficient power factor correction and thermal management for compact LED driver designs.

Feature Summary

• Integrates primary side regulation for simplified design without secondary feedback components
• Includes built-in 108 VDC brown-out detection for input voltage monitoring
• Supports analog dimming functionality for light control applications
• Features a soft-start resistor option to manage inrush current during startup

Applications

• Offline AC-DC LED lighting drivers
• Single-stage power factor corrected LED ballasts
• Compact LED lamp modules requiring primary side regulation

Procurement Notes

Verify the specific suffix DR2G against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Confirm end-of-life status or obsolescence notifications prior to finalizing procurement plans, as availability may be restricted. Ensure compatibility with existing bill of materials regarding the 7-SOIC footprint and pinout configuration.

Selection Notes

Select this component for applications requiring integrated PFC and CC/CV regulation in a single stage. It is suitable for designs prioritizing cost reduction through primary side regulation. Consider the 108 VDC brown-out threshold when designing for varying line voltages. Verify that the 500 mA output current range meets the target LED string requirements.

Part Context

This part belongs to onsemi's NCL30488 series of LED driver controllers. It is specifically engineered for high-performance, low-component-count LED lighting solutions. The series focuses on integrating multiple functions typically found in separate ICs to reduce system complexity and board space.

Replacement Considerations

Check for direct cross-reference part numbers from onsemi or other manufacturers offering identical 7-SOIC packages and PSR capabilities. Verify electrical parameter equivalence, particularly the brown-out threshold and maximum output current, before substitution.
