Hi Guys
Have question and plz someone help me to figure how to do .
I made an SMPS using the TL494 from a schematic attached .
the question is , To where should connect the remote ?
thanks

The REMOTE line is connected to the Vcc of the chip, so presumably you need to put the chip supply on that to get it working. What does the data sheet say?

Where did you get that schematic file from? I'm planning a push-pull converter myself, so I'm quite interested in such projects. Thank you.

Hi ,
This signal can be connected to the Battery. Remote is a seperate supply if you dont want to use the battery power. Some systems have seperate aux power for controller operation. In this case i am not sure why they have used it as seperate input.
you can short this with the battery.

The remote line should be loaded as little as possible. Some head units can't either handle too much current or too much capacitive load on the remote lead.

The best solution is to use a couple of transistors triggered by the remote signal to switch the power of the control IC and other circuits to +B.

Thank you Guys for the help .
First , Say's to connect the remote to car radio Antenna or to the
accessory pin so that can tell to run when turn the car radio on.
But this PS planed to use at home to power 2*100 watts 2* TDA7294
so there is no car radio to connect the remote with .
am going to short the remote with the Battery + pin that will be permanent or install a switch between them to power on demand .
The schematic got it from polish electronics producer .
can post the PCB and the part list if interested .
Thank you Diyer
Great site to learn from .
