产品名称：电流模式频率脉宽调制控制器
产品型号：ME8204
产品描述：
ME8204 is a highly integrated current mode PWM control IC optimized for high performance, low standby power (<100mW) and cost effective offline flyback converter applications in 40W～60W range. ME8204 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.
