NCL30082B3DR2G

Overview

The NCL30082B3DR2G is a dimmable quasi-resonant primary side current mode controller designed for LED lighting applications. It operates with flyback topology and supports an output current of 500 mA. The device functions within a supply voltage range of 8.2 V to 20 V, featuring a 12 V gate clamp. It integrates thermal foldback protection and operates at a frequency of 65 kHz. The component is housed in an SOIC-8 package and supports analog and PWM dimming capabilities.

Feature Summary

Integrates thermal foldback protection for enhanced reliability
Supports both analog and PWM dimming control methods
Utilizes quasi-resonant operation for efficiency optimization

Applications

Integral LED drive electronics
Dimmable LED lighting systems

Procurement Notes

Verify the specific suffix B3 against official datasheets to confirm pinout and electrical characteristics, as variations exist within the NCL30082 family. Confirm RoHS compliance status through manufacturer documentation. Ensure the SOIC-8 package dimensions match PCB layout requirements. Validate that the 8.2 V minimum supply voltage aligns with the target application's power stage design constraints.

Selection Notes

Select this component for designs requiring primary-side regulation with dimming support. The 500 mA output capability suits medium-power LED strings. Consider the 65 kHz switching frequency for magnetics design. Verify compatibility with the intended dimmer interface for analog or PWM signals. Ensure the operating temperature range meets environmental specifications.
