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.
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

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

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
Last Edit: Dec 20, 2015 4:05:11 GMT -8 by crazzzymick: no. of items requied two not one thanks
