The UCC24624DR from Texas Instruments is a high-performance, dual-channel synchronous rectifier (SR) controller specifically designed for LLC resonant converters. It replaces lossy diode output rectifiers with SR MOSFETs to enhance overall system efficiency.
This controller utilizes a drain-to-source voltage sensing method for precise on and off control of the SR MOSFETs. Key electrical specifications include a wide 4.25-V to 26-V VDD operation range and integrated gate drivers with 1.5-A source and 4-A sink capability for N-channel MOSFETs. It offers a fast 23-ns turn-off delay, supporting LLC operation above resonance up to 625-kHz switching frequency.
Features include proportional gate drive to extend SR conduction time and minimize body diode conduction, adjustable turn-off threshold, adaptive turn-on delay for better DCM ring rejection, and a two-channel interlock to prevent shoot-through. An automatic standby mode detection provides low standby current of 180 µA.
The UCC24624DR is available in an 8-pin SOIC package, suitable for surface mount applications. Its design aims to improve efficiency in power conversion systems.
