EM8569A

EM8569A HV Start-up Green-mode PWM Convertor with Brown-Out Protection General Description EM8569A is a high performance, low cost, HV Start-up, current mode PWM controller with green mode power saving. The EM8569A integrates functions of Soft Start (SS), Under Voltage Lockout (UVLO), Leading Edge Blanking (LEB), internal Over Temperature Protection (OTP), and internal slope compensation. The EM8569A also features more protection like Over Load Protection (OLP) and Over Voltage Protection (OVP) to prevent circuit damage occurred under abnormal conditions. The EM8569A also has line under-voltage protection (Brown-out Protection). Features 700V High Voltage Start up Circuit Current Mode Control Soft Start Function Built-in Slope Compensation Internal Leading-edge Blanking Brown in/out 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 ...
