TOP249Y Frequently Asked Questions (FAQs)

  • The maximum output power of the TOP249Y depends on the input voltage and the transformer turns ratio. However, it is typically limited to around 250W.
  • The transformer selection depends on the input voltage, output voltage, and output power. Power Integrations provides a transformer selection guide and a transformer design tool to help with the selection process.
  • The bootstrap capacitor (Cb) is used to provide a high-voltage supply to the gate driver of the power MOSFET. It is charged through the bootstrap diode (Db) during the off-time of the MOSFET.
  • The output voltage of the TOP249Y is set by the feedback resistors (Rfb1 and Rfb2) and the reference voltage (Vref). The output voltage can be calculated using the formula: Vout = Vref x (1 + Rfb2/Rfb1).
  • The overcurrent protection (OCP) pin is used to detect overcurrent conditions in the output. When the output current exceeds the set threshold, the OCP pin is pulled low, which triggers the shutdown of the TOP249Y.
