TOP246GN-TL datasheet by Power Integrations

TOP246GN-TL Frequently Asked Questions (FAQs)

• What is the maximum output power that the TOP246GN-TL can handle?
  The maximum output power of the TOP246GN-TL is 245W, but it can be derated based on the input voltage, output voltage, and ambient temperature.
• How do I ensure the TOP246GN-TL operates within its safe operating area (SOA)?
  To ensure the TOP246GN-TL 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.
• What is the purpose of the BYPASS pin on the TOP246GN-TL?
  The BYPASS pin is used to connect an external bypass capacitor to improve the power supply's noise immunity and electromagnetic compatibility (EMC). It is recommended to connect a 10nF to 100nF capacitor between the BYPASS pin and the primary side of the transformer.
• How do I choose the right transformer for the TOP246GN-TL?
  When selecting a transformer for the TOP246GN-TL, consider the input voltage, output voltage, and power rating. The transformer's turns ratio, magnetizing inductance, and leakage inductance should be compatible with the TOP246GN-TL's operating characteristics. Consult the datasheet and application notes for guidance.
• What is the purpose of the OVERCURRENT pin on the TOP246GN-TL?
  The OVERCURRENT pin is an open-drain output that goes low when the TOP246GN-TL detects an overcurrent condition. This pin can be used to trigger a fault response, such as shutting down the power supply or activating a fault indicator.
