EM8632

Green mode PWM Flyback Controller EM8632 General Description EM8632 is a high performance, low startup current, low cost, current mode PWM controller with green mode power saving. The EM8632 integrates functions of Soft Start(SS), Under Voltage Lockout(UVLO), Leading Edge Blanking(LEB), internal Over Temperature Protection(OTP), internal slope compensation. The EM8632 also features more protection like Over Load Protection(OLP) and Over Voltage Protection(OVP) to prevent circuit damage occurred under abnormal conditions. The EM8632 provides the users a superior AC/DC power application of high efficiency, excellent EMI performance, low external component counts and lower cost solution.
