TNY268PN Typical application Circuitry

TNY268PN

The TNY268PN is a specialized integrated circuit developed by Power Integrations, primarily used in power supply applications. It's part of the TinySwitch-III family, known for its efficiency and reliability in converting electrical power. This chip is commonly used in low-power AC/DC converter applications due to its built-in switcher and ability to handle power up to several watts.

Key Features of TNY268PN:

1. Integrated Switcher: Includes a power MOSFET and a controller in one package.

2. Energy Efficiency: Offers high energy efficiency, particularly at light loads.

3. Wide Operating Voltage Range: Acceptable input voltage range: wide.

4. Inbuilt Safety Measures: Consists of functions such as automatic restart, thermal shutdown, and overload protection.

5. Simple Circuit create: Makes it possible to create a power supply that is simpler and requires fewer external components.

6. Compact Size: Its small footprint is ideal for space-constrained applications.

7. Versatility: Can be used in both isolated and non-isolated power supply designs.

Application Scenario: LED Lighting Power Supply

In a LED lighting system, the TNY268PN can be used to design a compact and efficient power supply:

Detailed Circuit Connection:

1. Input Power Stage:

- AC Input Connection: Connect the AC power source to the input pins (DRAIN and SOURCE) of the TNY268PN, with a fuse in series for protection.

- Input Filter Capacitor: Place a capacitor across the AC input for filtering.

2. Transformer Coupling:

- Primary Winding Connection: Connect one end of the primary winding of a transformer to the DRAIN pin.

- Secondary Winding Setup: Connect the secondary winding to the rectifier and filtering circuit for the LED load.

3. Output Stage:

- Rectification and Filtering: Use a diode and capacitor on the secondary side of the transformer to rectify and filter the output voltage.

- LED Load Connection: Connect the output to the LED load.

Design Considerations of TNY268PN:

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

2. Safety Features: Implement overcurrent and thermal protection for safe operation.

3. EMI Considerations: Design the layout to minimize electromagnetic interference (EMI).

4. Optimal Component Selection: Select capacitors and diodes that can handle the required voltage and current levels.

5. Thermal Management: Ensure proper heat dissipation for the TNY268PN and other components.

Conclusion

Utilizing the TNY268PN in an LED lighting power supply highlights its capability to create compact, efficient, and reliable power solutions. Careful consideration of transformer characteristics, safety, EMI, component specifications, and thermal management is crucial in developing an effective power supply circuit for LED applications.
