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: TL594 Tool/software: Hello,
The datasheet of the TI's TL494 doesn't specify what happens with its outputs when the supply voltage is below the minimum required of 7V.
Is there some guarantee…
Part Number: TL494 Tool/software: Hello!
I would like to check my understanding concerning the resistor R5 and R7 in this reference design.
1) these resistors are used to reduce the gain to 101 compared to the open-loop gain. The reference sheet says…
Part Number: TL494 Tool/software: Hi,
I am looking to develop a PCB using one of Texas Instrument's pulse width modulator IC's for the purpose of cycling a MOSFET between closed and open to allow current to flow and stop flowing for certain periods…
Part Number: TL494 Tool/software: Hello guys,
One of my customers is evaluation TL494.
At this moment, they have the following questions. Could you please give me your reply?
Q1. Do you have any graph of DTC input voltage VS Dead time percentage?
Q2. In…
Part Number: TL494 Tool/software: Using TL494 IC to do a boost converter .
The input voltage is 100-250V, the output voltage is 300V, full load power is 250W.
The switchin frequency is 300kHz. And this is my schematic
And this is my MOSFET's Vgs and…
Part Number: TL494 Tool/software: Hi,
I've observed some unexpected behavior in TL494 and am trying to figure out what is causing it.
I'd like to share a schematic and explain. Is it possible to contact you via private message?
Thanks,
Conor …
