The CXAC85251O is a constant voltage constant current controller with high accuracy. CXAC85251O integrates high voltage power source, and can be supplied from line voltage directly, and auxiliary winding is not needed, which largely simplifies the system. Low standby consumption can be achieved with deep pulse frequency modulation. Critical conduction mode operation reduces the switching losses and largely increases the efficiency. CXAC85251O has multi-protection functions which largely enhance the safety and reliability of the system, including VCC over-voltage protection, VCC UVLO, LED short protection, pulse-by-pulse current limitand over-temperature protection.
