LT3751 Datasheet Capacitor Charger Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT3751 High Voltage Capacitor Charger Controller with Regulation.

General Description

The LT®3751 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 LT3751 has an integrated rail-to-rail MOSFET gate driver that allows for efficient operation down to 4.75V.
