CXAC85151 is a current Mode power controller, exhibit extra low standby power consumption (<100mW).PWM switching frenquency at normal operation is internally fixed. At no load or light load condition, it operates in hiccup mode to minimize switching loss.Lower standby power and higher conversion efficiency is thus achieved.
CXAC85151 offers power on soft start control and rich protection coverage with auto-recovery features including VDD under voltage lockout (UVLO), VDD over voltage protection (OVP), Cycle-by-Cycle current limiting (OCP), over load protection (OLP),over temperature protection (OTP), and line voltage brown-out protection.
