Introduction

AI Translation

SY5231 is a high-performance synchronous rectification controller which is suitable for CCM, DCM and QR mode flyback converter. It can drive standard and logic-level Nchannel MOSFET for secondary-side synchronous rectification. SY5231 adopts DSEN voltage falling slope rate detecting technology to avoid SR MOSFET false turn on by parasitic ring under DCM or QR mode. SY5231 adopts DSEN high voltage blanking time detective to enhance system ESD performance, it can prevent external noise false turn on SR MOSFET by making fast VDSEN falling slope rate. SY5231 features extremely short turn off delay time under CCM operating mode. Meanwhile, it uses DSEN voltage regulation technology to fully utilize conducting time of SR MOSFET for high efficiency under DCM or QR mode. Under light load condition, SY5231 will enter power save mode to improve light load efficiency. The SY5231 is available in a SOT23-6 package.
