The circuit generates high voltage from a low voltage battery to operate a photo-flash tube. The project can also be used in other applications like high voltage capacitor chargers, emergency strobe, high voltage power supply, security, detonators, etc.\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eLT3751\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eis the heart of the project.\u003c\/p\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eLT3751\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eis a high voltage input flyback controller designed to rapidly charge a large capacitor to a user-adjustable high target voltage set by the transformer turns ratio and three external resistors. Optionally, a feedback pin can be used to provide a low noise high voltage regulated output. The LT3751 has an integrated rail-to-rail MOSFET gate driver that allows for efficient operation down to 4.75V. A low 106mV differential current sense threshold voltage accurately limits the peak switch current. Added protection is provided via user-selectable overvoltage and under-voltage lockouts for both VCC and VTRANS. This project can charge a 220μF capacitor to 300V in less than one second. The CHARGE pin is used to initiate a new charge cycle and provides ON\/OFF control. The DONE pin indicates when the capacitor has reached its programmed value and the part has stopped charging.
