BL8851 Current Mode PWM Power Switch GENERAL DESCRIPTION BL8851 combines a dedicated current mode PWM controller. It is optimized for high performance, low standby power, and cost effective off- line flyback converter applications in 40W~60W range. BL8851 offers complete protection coverage with automatic self-recovery feature including Cycle- by-Cycle current limiting (OCP),CS short protection, CS floating protection, over load protection (OLP), and VDD under voltage lockout (UVLO), over temperature protection (OTP), over voltage(fixed or adjustable) protection (OVP). The tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during operation.. BL8851 is offered in SOT23-6 package.
