产品名称：电流模式PWM频率控制器

产品型号：ME8109

产品描述：

ME8109 integrates a PWM controller and high voltage power MOSFET of 600V or 650V. ME8109 has the features of very low standby power (<100mW) when AC power above 220Vac. and cost effective offline flyback converter applications in 18W range. ME8109 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 shufflingue 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.
