TOP245PN datasheet by Power Integrations

TOP245PN Frequently Asked Questions (FAQs)

• What is the maximum output power of the TOP245PN?
  The maximum output power of the TOP245PN is 245W, but it can be derated based on the input voltage, output voltage, and ambient temperature.
• How do I choose the right transformer for the TOP245PN?
  The transformer selection depends on the input voltage, output voltage, and power rating. A good starting point is to use the transformer design tool provided by Power Integrations or consult the application notes.
• What is the purpose of the BYPASS pin on the TOP245PN?
  The BYPASS pin is used to connect a bypass capacitor to improve the power supply's noise immunity and reduce electromagnetic interference (EMI).
• How do I implement overvoltage protection (OVP) with the TOP245PN?
  The TOP245PN has a built-in OVP feature that can be enabled by connecting a resistor and a zener diode between the OVP pin and the output voltage. The OVP threshold is set by the zener diode voltage.
• Can I use the TOP245PN in a non-isolated topology?
  No, the TOP245PN is designed for isolated topologies only. It is not suitable for non-isolated applications.
