TNY280PN Typical application Circuitry

TNY280PN

The TNY280PN is a specialized integrated circuit designed by Power Integrations, part of the TinySwitch-III series. It is a highly efficient off-line switcher IC, primarily used in power supply applications. This IC is commonly utilized in environments requiring the conversion of AC to DC power, such as in LED lighting systems, battery chargers, and small appliance power supplies.

Key Features of TNY280PN:

1. Integrated MOSFET: Comes with a built-in high-voltage power MOSFET for switching purposes.

2. Enhanced Energy Efficiency: Notable for its high energy efficiency, especially in low power or standby modes.

3. Wide Input Voltage Range: Capable of operating across various input voltages, making it versatile for global applications.

4. Built-In Protection Features: Includes auto-restart, thermal shutdown, and overload protection mechanisms.

5. Low External Component Requirement: Reduces the need for numerous external components, simplifying the power supply design.

6. Compact Form Factor: Its small size is ideal for applications where space is at a premium.

7. Application Flexibility: Suitable for both isolated and non-isolated power supply configurations.

Application Scenario: Compact LED Driver

In the context of a compact LED driver, the TNY280PN can be used to efficiently convert AC mains power to the appropriate DC output for LEDs.

Detailed Circuit Connection:

1. AC Input Stage:

- Mains Power Connection: Attach the AC mains to the DRAIN pin of the TNY280PN, ensuring the inclusion of a fuse in series for overcurrent protection.

- Input Filtering: Place a capacitor across the AC input for noise reduction.

2. Transformer Integration:

- Primary Winding Connection: Link one terminal of the transformer's primary winding to the DRAIN pin.

- Secondary Winding Output: Connect the secondary winding to a rectification and smoothing setup.

3. DC Output for LED:

- Rectification: Use a diode on the secondary side for AC to DC conversion.

- Smoothing Capacitor: Implement a capacitor post-rectification to stabilize the DC output.

- LED Load Connection: Finally, connect the output to the LED array.

Design Considerations:

1. Transformer Selection: Choose a transformer with an appropriate turns ratio for the desired LED voltage.

2. Circuit Safety: Implement essential safety features, including thermal and overcurrent protection.

3. EMI Considerations: Design the PCB to minimize electromagnetic interference, a vital aspect in LED drivers.

4. Component Ratings: Select capacitors and diodes with suitable voltage and current ratings.

5. Thermal Management: Plan for adequate cooling of the TNY280PN and other heat-generating components.

Conclusion

Utilizing the TNY280PN in a compact LED driver demonstrates its ability to deliver efficient and reliable power conversion in a small form factor. Key aspects such as transformer choice, safety features, EMI reduction, component selection, and thermal management play crucial roles in developing a successful LED power supply using this integrated circuit.
