EM8931

Cost Effective PWM Forward Controller EM8931 General Description EM8931 is a high performance, low startup current, low cost, current mode PWM controller. The EM8931 integrates functions of Soft Start(SS), Under Voltage Lockout(UVLO), Leading Edge Blanking(LEB), internal Over Temperature Protection(OTP), internal slope compensation. The EM8931 also features more protection like Over Load Protection(OLP) and Over Voltage Protection(OVP) to prevent circuit damage occurred under abnormal conditions. The EM8931 provides the users a superior AC/DC power application of high efficiency, excellent EMI performance, low external component counts and lower cost solution.
