Cxac85243 is a High-Performance AC / DC power controller, which can drive low-cost 1300 series NPN triode with PWM and PFM adaptive mode. The innovative low-power and fast start structure inside the chip solves the contradiction of slow power on and start-up in the current high-power system. At the same time, a variety of use fault and production fault protection circuits are built in, with high reliability.
Cxac85243, together with cxac85244 (or 431) and optocoupler, can precisely control constant voltage / constant current (CV / CC), which can realize stable operation of the system, greatly simplify the design of low and medium power CV / cc power converter, free of debugging, convenient for production, extremely low failure rate, and provide extremely strict accuracy of output voltage and current regulation.
Cxac85243 controller has low cost, high efficiency, low power consumption without load / fast startup speed: typical value of 20W circuit is 50mw/ 170ms@220Vac 。 Suitable for CV / cc power converter and adapter with output power of 0.5W-20W
