CXAC85152 CXAC85153 is a highly integrated current mode PWM controller,
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.Low startup current and low operating current contribute to a reliable
power on startup and low standby design with CXAC85152 CXAC85153.

CXAC85152 CXAC85153 offers complete protection coverage with auto-recovery
including Cycle-by-cycle current limiting (OCP), over load protection (OLP), and
VDD under voltage lockout (UVLO). It also provides the protections with latched
shutdown/auto-recovery including over temperature protection (OTP), over voltage
protection (OVP).
Excellent EMI performance is achieved with frequency spreading technique.
CXAC85152 CXAC85153 is offered in SOT23-6 package
