EM8557A Product details

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.

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). Features 600V High Voltage Start up Circuit Current Mode Control Soft Start Function Built-in Slope Compensation Internal Leading-edge Blanking Brown in/out Protection Over Voltage Protection (OVP) on VCC pin Over Load Protection (OLP) Cycle-by-cycle Current Limit Feedback Open P.
