The CXAC85252 is a high efficiency low cost off-line constant voltage regulator for Buck and BuckBoost topology with 700V MOSFET integrated. CXAC85252 can output 5V default voltage with few external components, which decreases the system cost. In light load condition, CXAC85252 operates in green mode, in which the inductor peak current and the switching frequency is lower than that of full load to improve the system efficiency and the reference voltage is decreased to ensure good load regulation. CXAC85252 has multi-protection functions which largely enhance the safety and reliability of the system, including VDD under-voltage Lockout (UVLO), short circuit protection (SCP), pulse-bypulse current limit, over load protection (OLP) and over-temperature protection (OTP).
