TDA7565 Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the TDA7565 is 2.5W, but it can be limited by the thermal resistance of the package and the PCB design. It's recommended to keep the junction temperature below 150°C to ensure reliable operation.
  • The input capacitor should be chosen based on the input voltage ripple, output voltage, and output current requirements. A general rule of thumb is to use a capacitor with a value of at least 10uF and a voltage rating of at least 2x the input voltage. Additionally, the capacitor's ESR (Equivalent Series Resistance) should be low enough to minimize voltage drops and ensure stability.
  • The bootstrap capacitor is used to generate the high-side gate drive voltage for the internal power MOSFET. It's connected between the BOOT pin and the VIN pin, and its value should be chosen based on the input voltage and the switching frequency. A typical value is 10nF to 100nF.
  • The output voltage of the TDA7565 can be adjusted by connecting a resistive divider between the VOUT pin and the GND pin, and connecting the center tap of the divider to the FB pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage (1.25V).
  • The minimum input voltage required for the TDA7565 to operate is 6.5V, but it's recommended to use an input voltage of at least 7V to ensure proper operation and to account for voltage drops in the system.
