The LT3750A is a flyback converter designed to rapidly charge large capacitors to a user-adjustable target volt-age. A patented boundary mode control scheme* minimizes transition losses and reduces transformer size. The transformer turns ratio and two external resistors easily adjust the output voltage.* A low 78mV current sense accurately limits peak switch current and also helps to maximize efficiency. With a wide input voltage range, the LT3750A can operate from a variety of power sources. A typical application can charge a 100μF capacitor to 300V in less than 300ms.

The CHARGE pin gives full control of the LT3750A to the user. The DONE pin indicates when the capacitor has reached its programmed value and the part has stopped charging.
