TNY278PN Typical application Circuitry

TNY278PN

The TNY278PN is an integrated circuit from Power Integrations, notable for its use in power conversion applications. It belongs to the TinySwitch-III series, designed for AC to DC conversion in compact power supplies. This chip is particularly favored in applications like LED drivers, battery chargers, and standby power supplies due to its high efficiency and integrated design.

Key Features of TNY278PN:

1. Integrated MOSFET: Includes a built-in high-voltage power MOSFET.

2. Energy-Efficient Design: Optimized for high efficiency, particularly in low-power modes.

3. Wide Operating Voltage Range: Capable of handling various input voltages.

4. Safety Features: Equipped with auto-restart, output overload protection, and thermal shutdown.

5. Compact Circuit Design: Allows for a simplified power supply with fewer external components.

6. Flexible Application: Suitable for both isolated and non-isolated configurations.

7. Low System Cost: Reduces overall system cost due to its integrated nature.

Application Scenario: Standby Power Supply for Consumer Electronics

In this scenario, the TNY278PN is utilized to design a standby power supply for a television, ensuring minimal power consumption when the TV is not in active use.

Detailed Circuit Connection:

1. AC Input Configuration:

- Mains Connection: Attach the AC mains to the DRAIN pin of the TNY278PN, with a fuse in series for overcurrent protection.

- Input Filtering: Place a capacitor across the AC input to reduce electrical noise.

2. Transformer Connection:

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

- Secondary Winding Output: Wire the secondary winding to a rectification and filtering setup.

3. Output Stage:

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

- Filtering Capacitor: Add a capacitor post-rectification to stabilize the DC output.

- Output to TV Circuit: Connect the output to the standby power input of the television.

Design Considerations:

1. Transformer Specification: Select a transformer that matches the required output voltage and current.

2. Circuit Protection: Implement necessary safety features, including thermal and overcurrent protection.

3. EMI Mitigation: Design the PCB to minimize electromagnetic interference, crucial in consumer electronics.

4. Component Ratings: Choose capacitors, diodes, and other components with appropriate voltage and current ratings.

5. Heat Dissipation: Ensure adequate cooling for the TNY278PN and other heat-generating components.

Employing the TNY278PN in a standby power supply for consumer electronics like a television showcases its efficiency in power conversion and its ability to maintain low power consumption in standby modes. Attention to transformer choice, circuit safety, EMI control, component specifications, and thermal management is key to developing a successful power supply using this IC.
