Overview
The NCL30080ASNT1G is a quasi-resonant primary side current-mode controller designed for LED drivers. It operates in off-line applications with a fixed frequency switching architecture that transitions to quasi-resonant mode to reduce switching losses. The device integrates protection features including over-voltage, over-current, and thermal shutdown. It supports compact designs by minimizing external component count while maintaining high efficiency and reliability across varying load conditions.
Feature Summary
- Implements current-mode architecture for precise control
- Operates in quasi-resonant mode to enhance efficiency
- Integrates comprehensive protection mechanisms
- Enables compact design with minimal external components
Applications
- Low wattage LED lighting fixtures
- A19 and GU10 lamp replacements
- Compact LED driver power supplies
- EMC-sensitive lighting applications
Procurement Notes
Verify the exact part number suffix against official onsemi documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Cross-reference the Mouser or distributor catalog numbers with the original manufacturer's ordering information to avoid substitution errors during procurement.
Selection Notes
Select this controller for applications requiring high efficiency in low-power LED systems. The quasi-resonant operation makes it suitable for designs where thermal management is critical. Ensure the input voltage range matches the specific AC line requirements. Consider the package type compatibility with the intended PCB layout constraints when finalizing the component selection.
Part Context
This component belongs to the NCL3008X family of controllers from onsemi. The family includes variants like NCL30081, NCL30082, and NCL30083, which share similar architectural features but may differ in specific pinouts or internal references. These controllers are positioned within the PMIC category for power management in lighting applications.
Replacement Considerations
Direct substitutes include other members of the NCL3008X family such as NCL30081ASNT1G, provided pin compatibility and electrical specifications align with the design requirements. Verify functional equivalence before swapping components.
