EM8557A
HV Start-up Green-mode PWM Convertor with Brown-Out Protection
General Description
EM8557A is a high performance, low cost, HV
Start-up, current mode PWM controller with green
mode power saving. The EM8557A integrates
functions of Soft Start (SS), Under Voltage Lockout
(UVLO), Leading Edge Blanking (LEB), internal Over
Temperature Protection (OTP), and internal slope
compensation. The EM8557A also features more
protection like Over Load Protection (OLP) and
Over Voltage Protection (OVP) to prevent circuit
damage occurred under abnormal conditions. The
EM8557A also has line under-voltage protection
(Brown-out Protection).
