SDC4108

Current Mode PWM Power Switch Datasheet SDC4108 General Description Features SDC4108 combines a dedicated current mode PWM Tcontroller with a high voltage power MOSFET. It is optimized for high performance, low standby power, and Ncost effective off-line flyback converter applications in Esub 16W range. MSDC4108 offers Complete protection coverage with automatic self-recovery feature including cycle-by-cycle Ucurrent limiting (OCP), over load protection (OLP), VDD Cover voltage clamp and under voltage lockout (UVLO). Excellent EMI performance is achieved with frequency Oshuffling technique, together with soft switching control Dat the totem pole gate drive output. The tone energy at below 22kHz is minimized in the design and audio noise CONFIDENTIALis eliminated during operation.  Power on soft start reducing MOSFET VDS stress  Frequency shuffling for EMI  Extended burst mode control for improved efficiency and minimum standby power design  Audio noise free operation ...
