TOP246P Frequently Asked Questions (FAQs)

  • The maximum allowed voltage on the BYPASS pin is 6.5V. Exceeding this voltage can damage the IC.
  • To ensure the TOP246P is in a low-power state during startup, make sure the voltage on the VCC pin is below 2.5V until the input voltage is stable. This prevents the IC from drawing excessive current during startup.
  • The SOURCE pin is used to sense the output voltage of the power supply. It is connected to the output of the transformer and provides feedback to the IC to regulate the output voltage.
  • No, the TOP246P is designed for use with isolated output topologies only. Using it with a non-isolated output can be dangerous and may cause electrical shock or damage to the IC.
  • The maximum output power of the TOP246P depends on the input voltage, output voltage, and transformer turns ratio. A general rule of thumb is to use the following formula: Pout = (Vin x Iin) / (η x (1 - D)), where Vin is the input voltage, Iin is the input current, η is the efficiency, and D is the duty cycle.
