一.产品概述  Ni7嘉泰姆

Ni7嘉泰姆

      JTMB8891  JTMB8892combines a dedicated current mode PWM controller with a high voltage power MOSFET. Ni7嘉泰姆

It is optimized for high performance,low standby power, and cost effective off-line flyback converter Ni7嘉泰姆

applications in sub 15W range.Ni7嘉泰姆

     JTMB8891 JTMB8892offers complete protection coverage with automatic self-recovery feature includingNi7嘉泰姆

Cycle-by-Cycle current limiting (OCP), over load protection (OLP), VDD over voltage clamp and underNi7嘉泰姆

voltage lockout (UVLO). Excellent EMI performance is achieved with proprietary frequency shuffling Ni7嘉泰姆

technique together with soft switching control at the totem pole gate drive output. The tone energy atNi7嘉泰姆

 below 20KHZ is minimized in the design and audio noise is eliminated during operation. Ni7嘉泰姆

    JTMB8891  JTMB8892 is offered in DIP-8 & DIP-7 package.Ni7嘉泰姆
