LINEAR TECHNOLOGY LT8309ES5#TRMPBF 芯片, 同步整流驱动器, TSOT-23-5
The is a secondary-side Synchronous Rectifier Driver that replaces the output rectifier diode in a fly back topology. By replacing the diode with a N-channel MOSFET, applications are no longer restricted by the heat constraints of the output diode. The IC replicates the behavior of a diode by sensing the drain-to-source voltage to determine when the current becomes negative. The LT8309"s low minimum on- and OFF-times help improve noise immunity. The fast propagation delay of 26ns allows applications to operate in discontinuous conduction mode DCM and critical conduction mode CrCM. The gate driver features a 0.8R pull-down device for fast turn-OFFs. The 40V VCC rating allows the part to be driven from the output voltage or the rectified drain voltage of the MOSFET. A low quiescent current of 400µA maximizes efficiency at low output currents.
