Shenzhen-Core Micro Technology Co., Ltd. Overview CX7156 is a high performance, highly integrated primary side sensing and regulating the use of the use of the AC / DC power supply control device. The components in the PFM mode constant current, PWM + PFM mode of constant pressure, in order to achieve excellent adjustability, and high efficiency, no optocoupler and secondary control circuitry. CX7156 has a built-in CC mode, the internal line loss compensation circuit voltage drop compensation circuit without external components. So that it has excellent constant current performance. CX7156 integrated power tube BJT, can further reduce system cost. It has built-in features and protection features a numeric keypad, so that it can minimize the number of external components, simplifies the EMI design and reduce overall costs. Application?
