Introduction

AI Translation

The LD7750R integrates several functions of protections, and EMI-improved solution in a SOP-7, 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 LD7750R 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 LD7750R features built-in auto-recovery function for OVP on Vcc pin and OLP.
