NCL30082BDMR2G

Overview

The NCL30082BDMR2G is a dimmable quasi-resonant primary side current-mode controller designed for LED lighting applications. It operates in flyback topologies with an adjustable output voltage and supports analog or digital dimming inputs. The device features thermal foldback protection and functions within a supply voltage range of 8.2 V to 20 V, delivering up to 500 mA output current. It utilizes SOIC-8 packaging and operates across a temperature range of -40°C to +125°C.

Feature Summary

• Primary side sensing eliminates the need for secondary feedback circuits, optocouplers, and bias windings.
• Supports both analog and digital dimming input methods for flexible control integration.
• Integrates thermal foldback protection to manage junction temperature under varying load conditions.

Applications

• Integral LED drive electronics
• Isolated AC/DC offline switchers
• Flyback converter designs for LED lighting
