TL494CDRE4 Frequently Asked Questions (FAQ)
-
The maximum switching frequency of TL494CDRE4 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 the TL494CDRE4 can be calculated using the formula: Vout = (R2 / R1) * (Vref - 2.5) + 2.5, where R1 and R2 are the resistors in the voltage divider network, and Vref is the reference voltage (typically 5V).
-
The dead-time control (DTC) pin on the TL494CDRE4 allows the user 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, the TL494CDRE4 can be used as a buck converter, but it requires an external transistor and diode to implement the buck converter topology. The TL494CDRE4 provides the necessary control signals for the transistor and diode.
-
The voltage drops in the TL494CDRE4 output stage can be compensated for by adding a voltage sense resistor (Rs) and a compensation capacitor (Cc) between the output voltage sense pin (VSENSE) and the output voltage. The values of Rs and Cc depend on the specific application and output voltage.
