Current Mode PWM Power Switch Freq Shuffling CXAC8577B CXAC8578combines a dedicated current mode PWM controller with a high voltage power MOSFET

   产品概述 返回TOP9nB嘉泰姆

    CXAC8577B   CXAC8578combines a dedicated current mode PWM controller with a high voltage power MOSFET. It is optimized for high performance, low standby power, and cost effective off-line flyback converter applications in sub 15W range. CXAC8577B   CXAC8578 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), VDD over voltage clamp and under voltage lockout (UVLO). Excellent EMI performance is achieved with proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output. The tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during operation. BCXAC8577B   CXAC8578is offered in DIP-8 & DIP-7 package.9nB嘉泰姆
