CXAC85164B is a highly integrated current mode PWM controller with high voltage start up,optimized for high performance, and low standby power. It is suitable for cost effective offline flyback converter applications.
PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range. In the condition of no load or light load, the IC operates in hiccup mode to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved.
High voltage startup is implemented in CXAC85164B, which features with short startup time and low standby current.
CXAC85164B offers complete protection coverage with auto-recovery including Cycle-by-cycle current limiting (OCP), over load protection (OLP), VDD under voltage lockout (UVLO),and over voltage (fixed or adjustable) protection (OVP). It also provides over temperature protection (OTP) with latched shutdown.

It also provides over temperature protection (OTP) with latched shutdown. Excellent EMI performance is achieved with frequency spreading technique.The tone energy below 22KHz is minimized in the design and audio noise is eliminated during operation.
