TL494CJ Frequently Asked Questions (FAQs)

  • The maximum switching frequency of the TL494CJ is 100 kHz, but it can be operated at higher frequencies with reduced output power.
  • To ensure stable operation, it is recommended to decouple the power supply pins (VCC and GND) with a 10uF capacitor, and to use a minimum of 100nF capacitor on the output (Vout) pin.
  • The dead-time control (DT) pin is used to adjust the dead-time between the high-side and low-side switches, which helps to reduce cross-conduction and improve efficiency.
  • Yes, the TL494CJ can be used as a synchronous rectifier by connecting the emitter of the low-side switch to the output (Vout) pin, and using the high-side switch as the synchronous rectifier.
  • The output voltage of the TL494CJ can be adjusted by changing the ratio of the resistors in the feedback network (R1 and R2) connected to the feedback (FB) pin.
