EM8672

HV Start-up PWM Controller with Over Temperature Protection

General Description

Features

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).
