CYStech Electronics Corp. Spec. No. : C151N6 Issued Date : 2012.11.08 Revised Date : Page No. : 1/11 Current Mode PWM Controller Description MC7773N6 is a highly integrated current mode PWM control IC optimized for high performance low standby power offline flyback converter applications. To meet the international power conservation requirements, optimized green mode is integrated to improve the efficiency at light or no load conditions with no audible noise. Slope pensation is integrated to ensure the stability at high load. Lead edge blanking is integrated to prevent the false trigger at the transition of the switch. Soft switching control at the gate drive can improve the EMI performance of the power supply. The Gate-drive output is clamped at 12V to protect the power MOS. Features - Frequency jitter function to improve EMI performance of power supply - No-audible-noise green mode control - Multi operation mode: Fixed-frequency CCM, green mode and burst mode. - No load input power under 100m W - Internal slope pensation - Low VDD startup current and low operating current - Leading edge blanking - UVLO 8.5V / 15.5V - Gate max output voltage clamp at 12V - Overload Protection (OLP) with auto-recovery - Line pensation over current protection (OCP) with auto-recovery - Over Temperature Protection (OTP) witch latch - VDD Over Voltage Protection (OVP) witch latch Applications Offline AC/DC flyback converter for - Battery Charger - Power Adaptor - Set-Top Box Power Supplies - Open-frame SMPS - PC 5V Standby Power Ordering Information Device MC7773N6 Package SOT-23-6L (Pb-free lead plating) Shipping 3000 pcs / tape & reel CYStek Product Specification CYStech Electronics...
