Overview
The NCL30085BDR2G is a quasi-resonant primary side current-mode controller designed for AC-DC LED drivers. It operates within an input voltage range of 9.4V to 26V and features a fixed switching frequency of 65kHz. The device supports external flyback topologies and provides constant current regulation for single-output LED applications. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SOIC-8 package.
Feature Summary
- Implements quasi-resonant operation to reduce switching losses and electromagnetic interference.
- Utilizes primary side regulation for accurate constant current control without secondary sensing components.
- Integrates auto-recovery timer functionality for enhanced fault protection and system reliability.
Applications
- AC-DC LED lighting drivers
- External flyback converter designs
- Constant current LED regulation
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'BDR2G' matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS directives and check for any end-of-life notices or obsolescence warnings prior to finalizing procurement plans.
Selection Notes
Select this controller for cost-effective, high-efficiency LED driver designs requiring primary-side regulation. It is suitable for applications where secondary feedback loops are undesirable. Consider the 65kHz frequency and SOIC-8 footprint when evaluating thermal management and PCB space constraints relative to alternative off-the-shelf solutions.
Part Context
This component belongs to the NCL30085 series from onsemi, specifically engineered for power factor correction and LED driving applications. It represents a specialized segment of the manufacturer's portfolio focused on efficient, compact AC-DC conversion solutions for solid-state lighting markets.
