EM8672

EM8672 HV Start-up PWM Controller with Over Temperature Protection General Description EM8672 is a high performance, low cost, HV Start-up, current mode PWM controller with green mode power saving. The EM8672 integrates functions of Soft Start(SS), Under Voltage Lockout(UVLO), Leading Edge Blanking(LEB), internal Over Temperature Protection(OTP), internal slope compensation. The EM8672 also features more protection like Over Load Protection(OLP) and Over Voltage Protection(OVP) to prevent circuit damage occurred under abnormal conditions. The EM8672 also has external Over Temperature Protection(Latch). Features 700V High Voltage Start up Circuit Current Mode Control Soft Start Function Built-in Slope Compensation Internal Leading-edge Blanking External Over Temperature Protection Over Voltage Protection (OVP) on VCC pin Over Load Protection (OLP) Cycle-by-cycle Current Limit Feedback Open Protection Internal Over Temperature Protection (OTP) Constant Output Power Limit (Full AC Input...
