EM8671A - Excelliance MOS

EM8671A PWM Controller

EM8671/A is a high performance, low cost, HV Start-up, current mode PWM controller with green mode power saving. The EM8671/A integrates functions of Soft Start(SS), Under Voltage Lockout(UVLO), Leading Edge Blanking(LEB), internal Over Temperature Protection(OTP), internal slope compensation. The EM8671/A also features more protection like Over Load Protec.

Features

more protection like Over Load Protection(OLP) and Over Voltage Protection(OVP) to prevent circuit damage occurred under abnormal conditions. The EM8671/A also has line under-voltage protection (Brown-out Protection).
