Cxac85198 is a high performance PWM controller designed for off-line flyback power supply. The chip has built-in original side constant current control technology, which is suitable for isolated power supply

Cxac85198 is a high performance PWM controller designed for off-line flyback power supply. The chip has built-in original side constant current control technology, which is suitable for isolated power supply application with constant current output. The cxac85198 has a high-precision 65khz switching frequency oscillator and a buffeting function. The chip adopts green energy-saving mode and burst mode to control light load and zero load. For applications less than 60W, it can guarantee standby power consumption less than 75MW. Cxac85198 has built-in complete protection functions: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle by cycle current limitation, short circuit protection (SCP), overload protection (OLP), overheat protection, soft start, VDD clamp, CS pin open circuit protection, etc
