General Description

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

Also, the LD7578J

Key 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.
