TL494IN Frequently Asked Questions (FAQ)
-
The maximum switching frequency of TL494IN is 100 kHz, but it can be operated up to 200 kHz with some limitations.
-
The values of RT and CT can be calculated using the formulae provided in the datasheet. Typically, RT is in the range of 1 kΩ to 10 kΩ, and CT is in the range of 100 pF to 1000 pF.
-
The DTC pin is used to control the dead time between the turn-off of one switch and the turn-on of the other switch in a push-pull converter. A lower voltage on the DTC pin reduces the dead time, while a higher voltage increases it.
-
To ensure stable operation, make sure to decouple the power supply pins (VCC and GND) with adequate capacitors, use a stable oscillator circuit, and provide a low-impedance power supply. Also, ensure that the layout is done carefully to minimize noise and electromagnetic interference.
-
Yes, the TL494IN can be used in a synchronous rectifier topology. However, additional circuitry is required to control the synchronous rectifier switches, and the TL494IN's output stage must be configured accordingly.
