  2. What is the maximum half-bridge switching frequency?
    The maximum half-bridge switching frequency is 500 kHz.
  3. What is the regulated supply voltage provided by the IC?
    The regulated supply voltage is 11.3 V at the SUPREG pin.
  4. What protection features are included in the TEA1716DB1255UL?
    The IC includes overtemperature, overvoltage, undervoltage, overcurrent protection, and safe restart mode.
  5. What are the operating modes of the TEA1716DB1255UL?
    The IC operates in burst mode switching and has an adaptive non-overlap time.
  6. What is the purpose of the integrated series stabilizer?
    The integrated series stabilizer creates an accurate regulated voltage for the internal drivers and external circuits.
  7. What applications is the TEA1716DB1255UL suitable for?
    The IC is suitable for LCD and plasma televisions, notebook adapters, high-power consumer electronics, and industrial power supplies.
  8. How does the IC manage power factor correction?
