TOP247YN Typical application Circuitry

TOP247YN

The TOP247YN is an integrated off-line switcher from Power Integrations, designed for high-efficiency power supplies. It combines a high-voltage power MOSFET with control circuitry into a single package, making it widely used in applications like AC to DC converters, power supplies for consumer electronics, LED drivers, and chargers.

Key Features of TOP247YN:

1. Integrated Power MOSFET: Includes a built-in 650V power MOSFET for efficient switching.

2. Extended Power Range: Suitable for applications requiring up to 250W.

3. Wide Operating Frequency: Reduces the size of the transformer and other components by operating at 132 kHz.

4. Line Under-Voltage (UV) Detection: Prevents turn-on at insufficient input voltages.

5. Hysteretic Thermal Shutdown: Provides reliable over-temperature protection.

6. Auto-Restart Feature: For open-loop and short-circuit fault scenarios.

7. Simple ON/OFF Control: Facilitates integration and control for a variety of applications.

8. Efficiency: Offers high efficiency necessary for energy-saving power supplies.

Application Scenario: Consumer Electronics Power Supply

Designing a power supply for a consumer electronic device like a TV set-top box using TOP247YN:

Detailed Circuit Connection:

1. AC Input and Rectification:

- AC Input: Connect the AC mains to a bridge rectifier. Then connect the rectified output to the DRAIN pin of the TOP247YN.

- Input Filter Capacitor: Place a capacitor between the rectified output and ground for smoothing.

2. Transformer Configuration:

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

- Auxiliary Winding: Use auxiliary winding to provide bias voltage to the CONTROL pin.

3. Feedback and Regulation:

- Optocoupler Feedback: Connect an optocoupler between the secondary winding and the CONTROL pin for voltage regulation.

- Voltage Reference: Use a Zener diode to set the reference voltage for the optocoupler.

4. Output Stage:

- Secondary Rectification: Use diodes to rectify the secondary winding output.

- Output Filter Capacitor: Place a capacitor after the rectification stage to filter the DC output.

- Output to Load: Connect the filtered output to the set-top box power input.

5. Protection Features:

- Overload Protection: Utilize the auto-restart feature of TOP247YN for overload protection.

- Thermal Protection: Rely on the hysteretic thermal shutdown feature for over-temperature protection.

Design Considerations:

1. Transformer Design: Select a transformer suitable for the required output power and voltage.

2. Component Quality: Use high-quality components, especially for capacitors and diodes, to ensure reliability and longevity.

3. EMI Compliance: Implement necessary filters and layout techniques to meet electromagnetic interference standards.

4. Thermal Management: Ensure adequate cooling for the TOP247YN, considering its power dissipation.

5. Safety Standards: Design the power supply to comply with safety standards relevant to consumer electronics.

6. Efficiency Optimization: Maximize efficiency to reduce energy consumption and meet regulatory requirements.

7. PCB Layout: Optimize the PCB layout for minimal noise and proper heat dissipation.

8. Regulatory Compliance: Ensure the power supply design complies with regulatory standards for consumer electronic devices.

Incorporating the TOP247YN into a power supply for consumer electronics, such as a TV set-top box, demonstrates its effectiveness as a compact, efficient off-line switcher. Key design aspects include proper transformer selection, high-quality component usage, EMI management, thermal considerations, compliance with safety and efficiency standards, strategic PCB layout, and adherence to regulatory requirements. This approach ensures the development of a reliable, efficient, and safe power supply for consumer electronics.
