常見問題解答

What is TOP209PN?

The TOP209PN is a three-terminal off-line PWM switch designed by Power Integrations. It is commonly used in power supply applications for offline power conversion, such as AC-DC power adapters, LED drivers, and auxiliary power supplies.

How Does TOP209PN Work?

The TOP209PN works by integrating a high-voltage power MOSFET with PWM control in a single package. It provides efficient power conversion by regulating the energy transfer from the input to the output using pulse-width modulation. The switch features a jittered switching frequency to reduce EMI emissions and improve efficiency.

How Many Pins does TOP209PN have and What are the Functions of the Pinout Configuration?

The TOP209PN is housed in a 7-lead through-hole package. The pinout configuration includes:

  • BP: Bypass Pin for the internal high-voltage DC bias.
  • DRIVE: Gate Drive Pin for controlling the internal power MOSFET.
  • FB: Feedback Pin for regulating the output voltage through an external optocoupler or feedback network.
  • COM: Common Pin serving as the return path for the internal power MOSFET and control circuitry.
  • RC: Resistor/Capacitor Pin for setting the oscillator frequency.
  • DM: Drain Pin for the internal power MOSFET.
  • S: Source Pin for the internal power MOSFET.

What are the Pros and Cons of TOP209PN?

Pros:

  • Integrated Solution: Combines high-voltage power MOSFET and PWM control in a single package, simplifying design.
  • High Efficiency: Provides efficient power conversion for offline applications, reducing power loss.
  • Jittered Switching Frequency: Helps minimize EMI emissions and improve conducted noise performance.
  • Wide Operating Input Voltage Range: Suitable for a variety of off-line power supply designs.

Cons:

  • Through-Hole Package: May require through-hole PCB design and soldering, potentially limiting surface-mount assembly options.
  • External Components: Some additional external components such as resistors and capacitors may be needed for specific applications.

Are There Any Equivalents/Alternatives to TOP209PN for Recommendation?

  • The TOPSwitch series from Power Integrations offers numerous alternatives, including TOP210PN and TOP204PN.
  • Equivalents to the TOP209PN include the LNK304 from Power Integrations and the FSD210 from Fairchild Semiconductor.
