TOP256YN Typical application Circuitry

TOP256YN

The TOP256YN is an integrated off-line switcher chip from Power Integrations, renowned for its efficiency and versatility in power supply applications. It combines a high-voltage power MOSFET with an extended power range, making it well-suited for applications such as AC to DC converters, power supplies for consumer electronics, LED drivers, and battery chargers.

Key Features of TOP256YN:

1. Integrated Power MOSFET: Includes a built-in high-voltage power MOSFET for effective switching.

2. Extended Power Range: Suitable for applications requiring up to 170W in open frame and 90W in adapter configurations.

3. Wide Operating Frequency: Operates at variable frequencies up to 132 kHz, which reduces transformer and power supply size.

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

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

6. Auto-Restart Feature: Ensures safe operation during fault conditions like open loop, short circuit, and overload.

7. EcoSmart Technology: Enables energy-efficient operation, especially under light-load and standby conditions.

8. Multi-Mode Operation: Supports both ON/OFF and PWM control for flexible application.

Application Scenario: Consumer Electronics Power Supply

Designing a power supply for a consumer electronic device, such as an LCD TV:

Detailed Circuit Connection:

1. AC Input and Rectification:

- AC Mains Connection: Attach the AC mains to a bridge rectifier, then connect the rectified output to the DRAIN pin of the TOP256YN.

- Input Filter Capacitor: Place a capacitor between the rectified output and ground to smooth the AC input.

2. Transformer Connection:

- Primary Winding: Link the primary winding of a transformer to the DRAIN pin of the TOP256YN.

- Secondary Winding: Connect the secondary winding to the output rectification and filtering circuit.

3. Feedback Loop:

- Optocoupler: Use an optocoupler between the secondary side and the CONTROL pin for feedback to regulate the output voltage.

- Voltage Reference: Implement a voltage reference, like a Zener diode, in the feedback loop.

4. Output Stage:

- Rectification: Utilize diodes to rectify the secondary winding's output.

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

- Output to Load: Connect the output to the power input of the LCD TV.

5. Protection Features:

- Overload Protection: Make use of the auto-restart function in the TOP256YN for handling overload conditions.

- Thermal Protection: Rely on the integrated hysteretic thermal shutdown for overheating safety.

Design Considerations:

1. Transformer Design: Opt for a transformer that matches the power and voltage requirements of the TV.

2. Component Quality: Use high-quality capacitors and diodes to ensure stability and longevity.

3. EMI Compliance: Incorporate necessary filtering to meet electromagnetic interference (EMI) standards.

4. Thermal Management: Plan for adequate heat dissipation for the TOP256YN.

5. Safety Protocols: Design according to safety standards applicable to consumer electronics.

6. Efficiency Optimization: Aim for high efficiency to reduce energy consumption and heat generation.

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

8. Regulatory Standards: Ensure the power supply meets regulatory standards for consumer electronic devices.

Incorporating the TOP256YN into a power supply for an LCD TV demonstrates its effectiveness in providing efficient, reliable power in a compact form factor. Key design aspects include transformer compatibility, quality component selection, EMI management, thermal considerations, safety compliance, efficiency optimization, strategic PCB design, and adherence to regulatory standards. This approach ensures a robust, high-performance, and safe power supply solution for consumer electronics.
