Cxac8592 is a highly integrated current mode PWM control chip, which can provide flyback applications with high performance, low standby power consumption and low cost. Under light load or no-load condition, the system enters into the green working mode, which reduces the switching loss, thus obtaining lower standby power consumption and higher conversion efficiency. The internal slope compensation circuit improves the system stability and reduces the subharmonic oscillation. The leading edge blanking function prevents the false triggering of MOSFET at the moment of opening, and reduces the peripheral circuit elements. Patented buffeting technology and output soft drive control technology greatly improve EMI characteristics
