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).
