NCL30488B4DR2G

Overview

The NCL30488B4DR2G is an LED lighting driver IC featuring a PFC quasi-resonant primary side current-mode controller with thermal foldback. It utilizes a flyback topology and provides one output capable of 500 mA. The device operates within a supply voltage range of 16 V to 20 V and supports dimming functions. It is housed in a SOIC-7 package and functions reliably between -40°C and +125°C.

Feature Summary

• Integrates primary side regulation for simplified design
• Includes thermal foldback protection mechanisms
• Supports analog dimming capabilities

Applications

• LED lighting systems
• Integrated LED bulbs
• LED tubes

Procurement Notes

Verify the specific suffix 'B4' against official datasheets to confirm exact electrical characteristics, as variations exist within the NCL30488 family. Confirm RoHS compliance status directly from manufacturer documentation prior to integration. Ensure the SOIC-7 package dimensions match your PCB footprint requirements exactly.

Selection Notes

Select this component for applications requiring primary side regulation combined with power factor correction. The integrated thermal foldback feature aids in maintaining reliability under varying load conditions. Verify that the 500 mA output current aligns with the target LED string configuration before finalizing the design choice.
