CX7538BS

CX7538BS is a high-performance secondary side synchronous rectification control circuit for switch-mode power <br/><br/>supplies. It easily meets the Level VI energy efficiency requirements in low-voltage, high-current switch-mode power <br/><br/>supply applications, making it an ideal solution for ultra-low forward voltage drop rectification devices. It also supports <br/><br/>various operating modes of switch-mode power supplies, such as CCM, QR , and DCM . Its extremely low forward <br/><br/>voltage drop results in much less conduction loss compared to Schottky diodes, greatly improving the system's <br/><br/>conversion efficiency and significantly reducing the temperature of the rectification device.<br/><br/><br/><br/>The CX7538BS chip features an NMOSFET synchronous rectification switch with a built-in voltage tolerance of 60V <br/><br/>and an extremely low internal resistance, with a typical RdsON as low as 12mΩ, providing the system with an output <br/><br/>capability up to 4A. The chip determines its switching state by detecting the source-drain voltage of the built-in <br/><br/>MOSFET, making it compatible with flyback converters in continuous mode, discontinuous mode, and quasi-resonant <br/><br/>operation modes.
