CXAC85251 high-precision constant voltage and constant current driver IC | Direct line voltage power supply | No auxiliary winding | Intelligent LED lighting solutions

CXAC85251 is a high-precision constant voltage and constant current drive controller designed for direct line voltage input (85V ~ 265V AC) scenarios, which can work without auxiliary windings, greatly simplifying the system architecture. Its integrated high-voltage power supply module supports critical conduction mode (Critical Conduction Mode), significantly reduces switching losses, and achieves high efficiency (>92%) over a wide voltage range. Low standby power consumption through deep pulse frequency modulation (PFM) technology80mW, and built-in LED short-circuit protection, cycle-by-cycle current limit, over-temperature protection and VCC overvoltage/undervoltage protection, provide high reliability and safety for intelligent lighting systems.
