SD484XP67K65

SD484XP67K65 CURRENT MODE PWM CONTROLLER WITH BUILT-IN HIGH VOLTAGE MOSFET DESCRIPTION SD484XP67K65 is a current mode PWM controller with low standby power and low start current for power switch. In standby mode, the circuit enters burst mode to reduce the standby power dissipation. The switch frequency is 67KHz with ±2.5 KHz jitter frequency for low EMI. SD484XP67K65 includes under voltage lock-out, over voltage protection, leading edge blanking, over current protection and the temperature protection. The circuit will restart automatically until the system is normal after the protection is active. FEATURES * Lower start-up current (Typ.6µA) * Frequency jitter for low EMI * Overcurrent protection * Overvoltage protection * Undervoltage lockout * Built-in temperature protection * Built-in high voltage MOSFET * Auto restart mode * Burst mode operation * Cycle by cycle current limit APPLICATIONS * Switch power HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: //www.silan.com.cn Downloa...
