TL494CNS Frequently Asked Questions (FAQs)

  • The TL494CNS can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value based on the switching frequency and output voltage requirements.
  • The DTC pin allows for adjustable dead time between the high-side and low-side switches, which helps reduce cross-conduction and improve efficiency.
  • Connect the external clock signal to the RT pin, and ensure the clock frequency is within the recommended range of 100 kHz to 500 kHz.
  • The TL494CNS can operate up to 500 kHz, but it's recommended to keep the switching frequency below 300 kHz for optimal performance and efficiency.
