Overview
The NCL30388A1DR2G is a power factor corrected flyback controller designed for isolated constant current LED drivers. It operates in quasi-resonant mode to minimize switching losses and acoustic noise. The device supports multiple topologies including Flyback, SEPIC, Buck, and Boost. It features an adjustable output voltage and delivers a supply current of 3400uA. Packaged in a 7-pin SOIC, it functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates power factor correction with quasi-resonant operation for high efficiency
- Supports isolated constant current LED driver applications
- Compatible with multiple converter topologies including Flyback and SEPIC
Applications
- Isolated constant current LED lighting systems
- Power factor corrected AC-DC converters
- General purpose flyback power supplies
Procurement Notes
Verify component status as the NCL30388A1DR2G is listed as obsolete by onsemi. Confirm availability through authorized distributors or approved substitute part numbers. Ensure compatibility with existing design constraints before procurement. Check for RoHS compliance documentation. Validate that replacement components meet original electrical specifications.
Selection Notes
Select this controller for designs requiring integrated PFC and quasi-resonant operation. Consider the 7-pin SOIC package for space-constrained layouts. Evaluate the 3400uA supply current against system power budgets. Verify support for required topologies such as Flyback or SEPIC. Assess thermal performance within the specified operating temperature range.
Part Context
Part of the NCL3038x series from onsemi, focusing on LED lighting drivers. This series targets efficient, compact power solutions for illumination applications. The NCL30388 variant specifically addresses isolated architectures with power factor correction requirements.
Replacement Considerations
