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.
Also, it 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.
