DESCRIPTION
●The LT®3750 is a flyback converter designed to rapidly charge large capacitors to a user-adjustable target voltage. 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 LT3750 can operate from a variety of power sources. A typical application can charge a 100µF capacitor to 300V in less than 300ms.
