TL494CDR Frequently Asked Questions (FAQs)

  • The maximum switching frequency of the TL494CDR is 100 kHz, but it can be operated at frequencies up to 200 kHz with reduced performance.
  • To ensure stable operation, make sure to decouple the power supply pins (VCC and GND) with a 10uF capacitor, and use a 1kΩ resistor in series with the output pin (OUT) to prevent oscillations.
  • The dead-time control pins (DTL and DTH) are used to adjust the dead-time between the high-side and low-side switches in a half-bridge configuration, allowing for optimization of switching losses and EMI performance.
  • Yes, the TL494CDR can be used as a push-pull converter by connecting the outputs (OUT) of two devices in a push-pull configuration, allowing for higher power density and improved efficiency.
  • The TL494CDR has a built-in overcurrent protection feature that can be enabled by connecting a resistor (ROC) between the ROC pin and GND, allowing the device to limit the output current in case of an overcurrent condition.
