LT3751EFE#PBF Description

LT3751EFE#PBF manufactured by Linear Technology/Analog Devices is a type of high input voltage capable flyback controller. A low noise high voltage regulated output is provided by a feedback pin. It is primarily designed to rapidly charge a large capacitor to a user-adjustable high target voltage set by the transformer turns ratio and three external resistors. Efficient operation down to 4.75V is allowed based on its integrated rail-to-rail MOSFET gate driver. The peak switch current is limited accurately through a low 106mV differential current sense threshold voltage.
