TOP250YN Typical application Circuitry

TOP250YN

The TOP250YN is an integrated off-line switcher from Power Integrations, designed for high-efficiency power supplies. Combining a high-voltage power MOSFET with control circuitry into a single package, it's widely used in applications like AC to DC converters, power supplies for consumer electronics, LED drivers, and chargers.

Key Features of TOP250YN:

1. Integrated Power MOSFET: Features an in-built 700V power MOSFET for efficient switching.

2. Extended Power Range: Suitable for applications requiring up to 90W.

3. Wide Operating Frequency: Operates at 132 kHz, allowing for smaller transformer size and other components.

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

5. Hysteretic Thermal Shutdown: Offers over-temperature protection.

6. Auto-Restart for Fault Conditions: Addresses open-loop, short-circuit, and overload conditions.

7. Energy-Efficient Design: Enables designs that meet strict energy-consumption standards.

8. Simple ON/OFF Control: Facilitates easy integration into various applications.

Application Scenario: LED Driver Power Supply

Designing a power supply for an LED lighting system using the TOP250YN:

Detailed Circuit Connection:

1. AC Input and Rectification:

- AC Mains Connection: Connect the AC mains to a bridge rectifier, then to the DRAIN pin of the TOP250YN.

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

2. Transformer Design:

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

- Secondary Winding: Use the secondary winding for the LED load.

3. Feedback and Regulation:

- Optocoupler: Connect an optocoupler between the secondary winding and the CONTROL pin for feedback.

- Voltage Reference: Use a reference like a Zener diode for accurate feedback control.

4. LED Load Connection:

- LED Array: Connect the LED array to the secondary winding of the transformer.

- Current Regulation: Implement current-sensing resistors for regulating the LED current.

5. Protection Features:

- Overload Protection: Utilize the auto-restart feature of the TOP250YN for managing overload conditions.

- Thermal Management: Use the hysteretic thermal shutdown as a safety mechanism.

Design Considerations:

1. Transformer Specification: Choose a transformer that matches the power requirements of the LED array.

2. Component Quality: Select high-quality capacitors and diodes for reliability.

3. EMI Management: Implement filtering to meet EMI standards.

4. Thermal Considerations: Ensure proper heat dissipation for the TOP250YN.

5. Safety Compliance: Design according to safety standards for LED lighting systems.

6. Efficiency Goals: Aim for high efficiency to reduce energy consumption.

7. PCB Layout: Optimize the PCB layout for minimal noise and efficient operation.

8. Regulatory Standards: Ensure the design complies with regulations for LED drivers.

Incorporating the TOP250YN into an LED driver power supply showcases its effectiveness as a compact, efficient switcher suitable for lighting applications. Key design aspects include appropriate transformer selection, use of quality components, EMI management, thermal handling, safety compliance, efficiency optimization, strategic PCB design, and adherence to regulatory standards. This approach ensures the development of a reliable, efficient, and safe power supply for LED lighting systems.
