LD7752 Datasheet | Leadtrend

Description The LD7752 brings high performance, highly integrated functions, protections and EMI-improve solution. It’s an ideal solution for those cost-sensitive system, reducing ponent count and overall system cost. The LD7752 features high voltage startup circuit, minimum loss and green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope pensation. They also consist of more protections of OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit from damage under abnormal conditions. Furthermore, the proprietary frequency swapping function can reduce the noise and help the power circuit designers to enhance EMI performance with fewer ponents and less developing time.
