LD7577J - High Voltage Green-Mode PWM Controller

Datasheet Summary

Description

The LD7577J integrated several functions of protections, and EMI-improved solution in a tiny package.

It minimizes the component counts and the circuit space, and it’s perfect for the low cost of applications.

Features

  • more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and brownout protection to prevent the circuit being damaged from the abnormal conditions. Furthermore, the LD7577J features frequency trembling to suppress the noise and is an excellent solution for EMI filter design. Features z High-Voltage (500V) Startup Circuit z Current Mode Control z Non-Audible-Noise Green Mode Control z UVLO (Under Voltage Lockout) z LEB (Leading-Edge Blanking) on CS Pin z Internal Frequenc.

LD7577J 8/16/2010 High Voltage Green-Mode PWM Controller with Brown-Out Protection Rev. 00b General Description The LD7577J integrated several functions of protections, and EMI-improved solution in a tiny package. It minimizes the component counts and the circuit space, and it’s perfect for the low cost of applications. It provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7577J features more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and brownout protection to prevent the circuit being damaged from the abnormal conditions.
