As voltage is stepped up by the transformer the current is stepped down. These values ipeak1 and ipeak3 are specified in product datasheet.

Application Notes And Circuits For Tps65552a Powers Portable

Basic xenon flash circuit theory explained.

Flash capacitor charger circuit. Disposable camera w flash. Before i begin talking about the schematic let it be known that there are four hardware blocks to this circuit. Photoflash capacitor charging circuit from disposable camera as a high voltage psu.

Like a battery the capacitor holds the charge until its hooked up to a closed circuit. 1 the wall transformer 2 the charger board connected to the capacitors 3 the voltage booster board 4 the led bank you can follow along with the picture as i will be extremely thorough with my hardware explanation. The lt3484s patented control technique allows it to use extremely small transformers and the improved npn power switch requires no external schottky diode clamp reducing solution size.

The 3rd circuit is a design i come up with to turn the hv output. The first design is one i come up with years ago when i built a few hv photo flash capacitor chargers this is based on another circuit which i had to make some changes to suit my hv cap charger the next circuit is what mine was based on you can see how different they look now they are photo flash cap charger indicator circuits. The capacitor is connected to the two electrodes on the flash tube at all times but unless the xenon gas is ionized the tube cant conduct the current so the capacitor cant discharge.

Momentary push button switch. A few square inches of 14 thick wood acrylic glass etc. The lt3484 family of photoflash capacitor charger ics is designed for use in digital camera and mobile phone applications where space is at a premium.

Syringe tips come with ink cartridge refill kits. The tps65573 stops charging when the voltage at photo flash capacitor achieves the target voltage. The flash circuit stores this high voltage charge in a large capacitor.

The target output voltage is set by the turn ratio of transformer. Soldering iron and solder. Thats why it takes several seconds to charge the capacitor.

Simply connecting an aa cell to any capacitor would only allow it to charge to nearly 15v. Including demonstration for the triggering stages and capacitor discharge. The wall transformer booster and led bank are all stand alone products.

The oscillator circuit draws quite a large current from the cell thats why batteries dont last long in flash guns. Super glue hot glue. The tps65573 can detect it at primary side of the transformer via transformer.
