■ DESCRIPTIO 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. Charges Any Size Capacitor
