Part Number: TL494 Other Parts Discussed in Thread: TL594 Tool/software: Dear Experts,
We want to use TL494 or TL594 as a constant current source and would like to know if the output PWM duty cycle of these two chips can be adjusted to over 95%, and…
Hi,
I already replied to you as the circuit cannot work since Q82 and Q81 either on or off, then R26 sensed voltage is either 0 or high, so voltage R26 is step up and down, TL494 cannot work with such step up and down voltage as feedback.
Part Number: TL494 Tool/software: Hello everyone! After updating to LTSpice24, I encountered an error with the TL494 simulation. I made the following changes from the model available online: Line 6: V§DT N007 DTC 0.12 was corrected to V1 N007 DTC…
Part Number: TL494 Tool/software: Hi,
I am designing a PWM generator that its frequency and duty cycle are adjustable. I am trying to produce low frequency PWM signals as low as 10Hz and the lowest duty cycle as possible. In my application I observe…
Part Number: TL494 Other Parts Discussed in Thread: CSD19538Q3A , TPS2816 , TPS2828 , TPS2818 Tool/software: Hello,
I have a VDD = 46V which supplies a system (load). This load tries to draw more than 10A, and I want to limit the current. For this, I wanted…
Part Number: TL494 Tool/software: Hi, TI team,
I'm gonna design a circuit to convert power like follows.
-. Input : 12V DC,
-. Output : Bipolar +65V, -65V / 1kW
The application is for supplying Power to Audio Amplifier .
I appreciate it if you…
Part Number: TL494 Tool/software: Hi TI Team,
The customer encountered the following problems when using TL494 to design the laser power supply, please help to see if the adjustment loop parameters can be improved?
When the AC input is 220V, the current…
Part Number: TL494 Other Parts Discussed in Thread: LM25037 , LM5030 Tool/software: Hi,
i want to design 27V/1A isolated DC to DC converter using TL494 can you suggest a circuit diagram
Part Number: TL494 Other Parts Discussed in Thread: LM393 , UCC2894 , UCC2897A Tool/software: Hi, I need to design a 12V 200W ATX power supply for my own needs, based on various diagrams I see that the power goes to the TL494 module and then to the LM393…
