Cxac85110 is a high-performance and low-power CC / CV switching power driver chip based on 700V high-voltage technology. Using the principle of primary side feedback, it can eliminate secondary optocoupler, TL431 and other control circuits. The cxac85110 adopts a novel adaptive peak regulation technology, which can automatically adjust the change of the original peak current according to the output power, greatly accelerating the dynamic response and providing excellent constant voltage performance. Cxac85110 can also compensate the output line loss and make up the voltage drop loss of the output voltage on the output line to achieve good load regulation. In addition, the built-in buffeting technology of cxac85110 chip effectively improves the EMI performance of the system.
Cxac85110 has multiple protection functions, including VDD undervoltage protection, VDD voltage clamping, cycle by cycle peak current limitation, output on / short circuit protection, chip overheat protection, etc., providing better protection measures
