TL494INE4 Frequently Asked Questions (FAQs)

  • The maximum switching frequency of TL494INE4 is 100 kHz, but it can be operated up to 200 kHz with some limitations on the output power and voltage.
  • The output voltage of TL494INE4 can be calculated using the formula: Vout = (R2 / R1) * (Vref * (1 + R3 / R4)), where R1, R2, R3, and R4 are the resistors in the feedback network, and Vref is the reference voltage (typically 2.5V).
  • The dead-time control pins (DT/CMP) in TL494INE4 are used to adjust the dead time between the turn-off of one switch and the turn-on of the other switch in a push-pull converter. This helps to prevent shoot-through currents and reduce EMI.
  • Yes, TL494INE4 can be used for isolated DC-DC converters, such as flyback or forward converters, by using a transformer and a suitable feedback network to regulate the output voltage.
  • The values of the output filter components (L and C) in TL494INE4 depend on the output voltage, current, and frequency. A good starting point is to use the following formulas: L = (Vout * (1 - D)) / (ΔI * fsw), and C = (Iout * D) / (ΔVout * fsw), where D is the duty cycle, ΔI is the ripple current, and ΔVout is the output voltage ripple.
