LD7750
Description
The LD7750 integrates several functions of protections, and EMI-improved solution in a SOP-8, SOP-7, or DIP-8 package to minimize the ponent counts and the circuit space. The device provides functions of low startup current, green-mode pensation. Voltage power-saving Also, the operation, LD7750 OTP leading-edge features more blanking of the current sensing and internal slope protections like OLP (Over Load Protection), OVP (Over Protection), and (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7750 features built-in auto-recovery function for OVP on Vcc pin and OLP. Furthermore, the LD7750 features frequency swapping to depress radiation noise, providing an excellent solution for EMI filter design.
