Product Overview

The LT3750EMS#PBF is a Capacitor Charger Controller designed to rapidly charge large capacitors to an 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. The CHARGE pin gives full control of the LT3750 to the user. The DONE pin indicates when the capacitor has reached its programmed value and the part has stopped charging. Operation proceeds in four phases, start-up, primary-side charging, secondary energy transfer and discontinuous mode sensing. The flyback transformer is critical to proper operation of the LT3750.
  • Charges any size capacitor
  • Easily adjustable output voltage
  • Drives high current NMOS FETs
  • Primary-side sense, no output voltage divider necessary
  • Drives gate to -2V VCC
