EM8671/A

HV Start-up Green-mode PWM Controller with Brown-Out Protection

General Description

Features

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

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).
