CXAC8507A/B integrates a PWM controller and high voltage power MOSFET of 600V or 650V. CXAC8507A/B has the features of very low standby power (<100mW) when AC power above 220Vac. and cost effective offline flyback converter applications in 18W range. CXAC8507A/B offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), CS short protection, over load protection (OLP), and VDD under voltage lockout (UVLO) and latch feature including over temperature protection (OTP), over voltage (fixed or adjustable) protection(OVP). Excellent EMI performance is achieved with frequency shuffling technique together with soft switching control at the totem pole gate drive output. Tone energy at below 20KHz is minimized in the design and audio noise is eliminated during operation
