General Description

The LD7577 integrates several functions of protections, and EMI-improved solution in SOP-8 package.

It minimizes 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.

Key Features

more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and brownout protection to prevent the circuit from being damaged under abnormal conditions.
