一.产品概述  3mc嘉泰姆

3mc嘉泰姆

         JTMB8836  JTMB8836A is a high performance offline PWM Power switch for low power AC/DC charger and adapter

applications. It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could3mc嘉泰姆

 be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in3mc嘉泰姆

 the figure below.3mc嘉泰姆

    Fig.1. Typical CC/CV Curve3mc嘉泰姆

      In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs3mc嘉泰姆

at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency.3mc嘉泰姆

 In addition, good load regulation is achieved by the built-in cable drop compensation.Device operates in PFM3mc嘉泰姆

 in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load.3mc嘉泰姆

      JTMB8836  JTMB8836A offers power on soft start control and protection coverage with auto-recovery features3mc嘉泰姆

 including Cycle-by-Cycle current limiting, VDD OVP,VDD clamp and UVLO. High precision constant voltage (CV) 3mc嘉泰姆

and  constant current (CC) can be achieved by JTMB8836  JTMB8836A.3mc嘉泰姆
