CL1152 is a combination of a current-mode PWM controller and high-voltage power MOSFET AC-DC chip. CL1152 with high integration, low power consumption, high efficiency and other characteristics, mainly used in power at 20W or less isolated occasions. CL1152 integrated soft-start function, CS side leading-edge blanking (LEB), by-cycle current limit function (OCP), overload protection (OLP), undervoltage lockout (UVLO). CL1152 uses a frequency jitter and soft drive control and improve the system EMI performance. Features ◆ high-voltage CMOS process and a good ESD protection ◆ ◆ low starting current frequency jitter EMI problem solving ◆ No audio noise green-mode control ◆ 50kHZ fixed switching frequency harmonics slope compensation ◆ ◆ Built-in Built-in leading edge blanking (LEB ) ◆ ◆-by-cycle current limiting undervoltage lockout (UVLO) ◆ VDD OVP protection ◆ overload range of applications low power AC-DC switching power off applies: ◆ ◆ Small Power Adapter PC / TV auxiliary power ◆ linear power Alternative CL1152 package for DIP8
