TNY274PN Typical application Circuitry

TNY274PN

The TNY274PN is a specialized integrated circuit from Power Integrations, belonging to the TinySwitch-III family. It's designed primarily for power supply applications, combining a power MOSFET and a controller into a single package. This IC is frequently used in applications requiring efficient AC to DC conversion, such as chargers, standby power supplies, and LED drivers.

Key Features of TNY274PN:

1. Integrated Power MOSFET: Contains an in-built high-voltage power MOSFET for switching.

2. Enhanced Energy Efficiency: Provides high efficiency, especially critical at low power levels.

3. Wide Operating Voltage Range: Suitable for a variety of input voltages.

4. Built-in Protection Mechanisms: Features include auto-restart, output overload protection, and thermal shutdown.

5. Minimal External Components: Designed for use with a minimal number of external components, simplifying circuit design.

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

7. Flexibility in Applications: Appropriate for both isolated and non-isolated power supply designs.

Application Scenario: Standby Power Supply for a Television

The TNY274PN is used in designing a standby power supply for a television, ensuring minimal power consumption when the TV is not in active use:

Detailed Circuit Connection of TNY274PN:

1. AC Input Stage:

- AC Power Connection: Connect the AC mains to the DRAIN pin of the TNY274PN through a series fuse for protection.

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

2. Transformer Coupling:

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

- Secondary Winding for Output: The secondary winding is connected to a rectification and filtering circuit.

3. Output Stage for Standby Power:

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

- Filtering Capacitor: Add a capacitor to smooth out the rectified DC voltage.

- Connection to TV Circuit: The output is then connected to the standby circuit of the television.

Design Considerations of TNY274PN:

1. Appropriate Transformer Selection: Select a transformer with the correct turns ratio for the required output voltage.

2. Safety and Protection: Ensure proper implementation of overcurrent and thermal protection.

3. Minimizing EMI: Layout the PCB to reduce electromagnetic interference.

4. Component Ratings: Choose capacitors and diodes rated for the appropriate voltage and current.

5. Thermal Management: Design for adequate heat dissipation of the TNY274PN and other heat-generating components.

Conclusion

Employing the TNY274PN in a standby power supply for a television showcases its capability to deliver efficient, low-power conversion in a compact form factor. Critical considerations for this application include transformer characteristics, safety protocols, EMI reduction, selection of components with appropriate ratings, and effective thermal management.
