NCL2801CDADR2G Typical application Circuitry

NCL2801CDADR2G

NCL2801CDADR2G is an advanced, highly integrated, Primary-Side Regulated (PSR) flyback controller from ON Semiconductor, designed for efficient and compact AC-DC power conversion in applications such as LED lighting, auxiliary power supplies, and battery chargers. This controller enables designs with minimal external components, due to its PSR technique that eliminates the need for an optocoupler, and features such as adjustable output voltage and current, high power factor, and low standby power consumption.

Application Scenario: LED Lighting Power Supply

A common application for the NCL2801CDADR2G is in the power supply units for LED lighting systems, where it offers a compact, efficient, and reliable solution for converting AC mains power to the low-voltage DC power required to drive LED arrays.

Parameter Features

- Primary-Side Regulation: Eliminates the need for secondary-side feedback, reducing component count and simplifying the design.

- High Power Factor: Ensures efficient power usage and compliance with regulatory standards for lighting applications.

- Adjustable Output Voltage and Current: Enables precise control over LED brightness and color consistency.

- Integrated Protections: Features overvoltage, overcurrent, and thermal shutdown protections to enhance safety and reliability.

Detailed Circuit Connection for LED Lighting Power Supply

AC Input Stage

Connect the AC mains input to the L and N terminals, passing through a fuse and EMI filter before reaching the bridge rectifier. The rectified output is then connected to the VIN pin (Pin 1) of the NCL2801CDADR2G, providing the high-voltage DC input required for the flyback conversion.

Transformer and Switching Configuration

The GATE pin (Pin 6) drives the primary winding of the flyback transformer via an external MOSFET. The transformer's secondary winding is connected to the LED load, with the transformer's auxiliary winding providing feedback to the FB pin (Pin 5) for primary-side regulation.

Feedback and Regulation

The VSENSE pin (Pin 2) is connected to a resistor divider network on the primary side, sensing the output voltage indirectly. This setup, combined with the feedback from the auxiliary winding, allows the NCL2801CDADR2G to regulate the output voltage and current to the LEDs without secondary-side feedback.

Protection Features Implementation

Connect a resistor from the CS pin (Pin 4) to the source of the external MOSFET for overcurrent protection. The NCL2801CDADR2G's built-in thermal shutdown and overvoltage protection further ensure the safety and reliability of the power supply.

Design Considerations

When designing an LED lighting power supply with the NCL2801CDADR2G, consider the following key factors:

- Transformer Design: Carefully design the flyback transformer to meet the power requirements of the LED load while ensuring efficient energy transfer and proper feedback for the PSR control.

- Component Selection: Choose high-quality components, especially for the external MOSFET, diodes, and capacitors, to ensure efficiency, reliability, and longevity under varying load and temperature conditions.

- Thermal Management: Evaluate the thermal performance of the NCL2801CDADR2G and associated power components, implementing heat sinks or thermal vias as necessary to maintain optimal operating temperatures.

- EMI and Safety Considerations: Implement appropriate EMI filtering and adhere to safety standards, considering the isolation requirements between the AC input and the low-voltage output side.

Incorporating the NCL2801CDADR2G into LED lighting power supplies allows designers to achieve compact, efficient, and reliable solutions, enhancing the performance and energy efficiency of modern LED lighting systems.
