LT LT3751IUFD#PBF

照相机闪光灯电容器充电器5.5mA4.75V ~ 24V

Overview

The LT3751IUFD is a high input voltage capable 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 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. The FAULT pin indicates when the LT3751IUFD has shut down due to either VCC or VTRANS voltage exceeding the user-programmed supply tolerances.
