I am totally intrigue with the switch mode strobe circuit using the TL594 IC Is A circuit break down available. I am looking at pin 13 of the TL594 if this is low does that turn off Q1 and Q2? |

This Circuit is designed so that if the Supply Voltage Goes Below 11 Volts or if it Goes above 15.5 Volts, The Circuit Shuts OFF. Sorry I Don't normally do Write-Ups on the Detailed functions. No Pin 13 is Just a Reference Voltage. If the Supply Voltage goes too high or Low, The Error Amplifiers on Pins 1, 2 & 15, 16 Determine an output to Pin 3. And If Pin 3 goes High, the Unit Shuts down. A VIDEO of this Strobe in Operation: Strobe-2 |

Had some time to study the inside working of the TL594 Pulse-Width-Modulation Control Circuit IC from Texas Instrument data.
Gary Lecomte circuit using the TL594 is well design His printed circuit board and transformer is well suited for my needs. I will be ordering a board + transformer this week end.
Keep up the good work Gary I will be posting on Tuesday Thanks

Thanks Gary the circuit broad and transformer + IC has just arrived to day will buy the rest of the components tomorrow.
Thanks keep up the good work

Finally I can make a start on this project I am wondering would it be safe to operate the primary side
oscillator circuit + transformer primary without a secondary wound on the transformer. I appreciate there
would no load on the primary circuit but I have always built things in stages and I am just a bit worried
about the IC and the power mosfet I cannot see any problems but I thought I ask.
Thanks Gary

No it Shouldn't cause any Problem.

Thanks Gary.
The projects worked as intended as the strobe at 12V. I am now using your board as a switching
high voltage power supply similar to your switching power supply as the circuits are very similar but the
transformer is on the main board as it suits me better. I now am requiring two more strobe switching boards
and two more transformer core + bobbin If this is possible could you give me a price for these items if
they are still available
Thanks Gary

Possibly, But You Need to Email Me about this.
NOTE: I will be Away on a Holiday to Chile, South America From Approximately Jan 15 to Feb 15.
