TOP249YN Frequently Asked Questions (FAQ)

  • The maximum output power of the TOP249YN is 250W, but it can be derated based on the input voltage, output voltage, and ambient temperature.

  • To ensure the TOP249YN operates within its SOA, follow the guidelines in the datasheet for input voltage, output voltage, output current, and ambient temperature. Also, make sure to provide adequate heat sinking and thermal management.

  • The BYPASS pin is used to connect a bypass capacitor to the internal voltage regulator. This helps to reduce the noise and ripple on the internal voltage regulator output, ensuring stable operation of the TOP249YN.

  • When selecting a transformer for the TOP249YN, consider the input voltage, output voltage, and power rating. The transformer should be designed to handle the maximum output power of the TOP249YN, and its turns ratio should be chosen to achieve the desired output voltage.

  • The OVP (Over-Voltage Protection) pin is used to detect over-voltage conditions on the output. When the output voltage exceeds the OVP threshold, the TOP249YN will shut down to protect the load and itself from damage.
