LD7578J - High Voltage Green-Mode PWM Controller

Description

The LD7578J integrates several functions of protections, and EMI-improved solution in a SOP-8/or DIP-8 package to minimize the component counts and the circuit space.

Features

  • more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7578J features built-in auto-recovery function for OVP on Vcc pin and OLP. Furthermore, the LD7578J features frequency trembling to depress radiation 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 Mo.

LD7578J 03/03/2009 High Voltage Green-Mode PWM Controller with Over Temperature Protection Rev. 00 General Description The LD7578J integrates several functions of protections, and EMI-improved solution in a SOP-8/or DIP-8 package to minimize the component counts and the circuit space. The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7578J features more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7578J features built-in auto-recovery function for OVP on Vcc pin and OLP.
