TL494 Duty Cycle - All About Circuits
2010年4月30日 · The TL494 is by default a push-pull controller, which is why it has 2 switching transistors. It turns on one transistor for some duty cycle, then the other. With 100% duty cycle for a single transistor you still only get 50% because it alternates.
Current stabilization for TL494 - All About Circuits
2012年11月22日 · The diagram you have wont work,as its using the deadtime pin to regulate. To put current limit on a TL494 you need to use pin 16 or pin 1 to detect the increased current through a series resistor in the source load of the mosfet, try a 0.1 ohm resistor so at 20amps thats 2volts across the resistor, so if you put a 1 k pot also across the resistor with the wiper to …

TL494/594 Buck converter timebase distorted - All About Circuits
2023年10月19日 · Curiously enough, the clock seems to be as stable as it could be (it is determined by the R_T / C_T combination on two pins of the TL494). However, the C_T ramp has noise exactly at the points of PWM signal switch-on and off- (caused by the very switching, as it seems from the time sequence), which is enough to cause it to throw a false pulse.

2023年10月19日 · All the TL494-based switch-mode PSUs I've seen use BJTs as switching devices. As the datasheet states: "Two output transistors are available on the TL494. Both transistors are configured as open collector/open emitter, and each is capable of sinking or sourcing up to 200 mA. The transistors have a saturation voltage of
Tl494+IR2110 - All About Circuits
2020年1月2日 · Hello everyone in the AAC community. I recently built this motor controller based on TI's TL494 and IR2110 mosfet driver. Although it works great i have a question. I have the ir2110 configured as a dual low side driver and both motors work, if i where to place both motor on the same shaft to...
