General Description

EM8569D is a high performance, low cost, HV

Start-up, current mode PWM controller with green

mode power saving. It integrates an advanced

PWM and 700V power MOSFET a single package,

provides the users a superior power designs with

higher efficiency, reduced size, improved reliability,

and lower power system cost.

The EM8569D also features more protection

like Over Load Protection (OLP) and Over Voltage

Protection (OVP) to prevent circuit damage

occurred under abnormal conditions. And has line

under-voltage protection (Brown-out Protection).
