UCC24636 Synchronous Rectifier (SR) Controller Texas Instruments UCC24636 Synchronous Rectifier (SR) Controller is a compact, 6-pin secondary-side synchronous rectifier MOSFET controller and driver. This controller is designed for high efficiency Flyback converters operating in Discontinuous (DCM) and Transition mode (TM). Unlike traditional SR controllers which measure the SR MOSFET drain voltage, UCC24636 implements a volt-second balance control method to determine the turn off transition of the SR MOSFET. This method makes the conduction time independent of the MOSFET RDSON, parasitic inductance or ringing allowing flexibility to designers in component slelction and PCB layout. This control method enables maximum SR conduction time and highest rectifier efficiency for a given MOSFET.
