Cxac85178 is a high performance off-line PWM switch controller, mainly used for AC-DC small power charger and adapter. There are two ways of original edge detection and feedback

Cxac85178 is a high performance off-line PWM switch controller, mainly used for AC-DC small power charger and adapter. There are two ways of original edge detection and feedback, without optocoupler and TL431, constant voltage (CV) and constant current (CC). Under CC control, current and output power can be adjusted through external isen foot resistance). Under CV control, multi-mode operation can achieve high performance and efficiency. It works in PFM mode and CC mode under heavy load and PWM mode under no load and light load. Cxac85178 provides comprehensive protection, such as weekly limit current detection (OCR), OVP, UVLO, which can wake up automatically after the protection is removed.
