AC-DC控制器 : 转移模式功率因数修正控制器

The LD7591 is a voltage mode PFC controller operating on transition mode, with several integrated functions of protection, such as OVP, OCP, and Brown-in protection. It reduces the components counts and is available in a SOP-8 or DIP-8 package.Those make it an ideal design for low cost applications. • Transition mode of PFC pre-regulator\n• Voltage mode control\n• Programmable max. on-time\n• Low Startup Current (<30μA)\n• UVLO (Under Voltage Lockout)\n• LEB (Leading-Edge Blanking) on CS Pin\n• Open-Feedback Protection and Disable Function\n• OVP (Over Voltage Protection)\n• OCP (Cycle by cycle;
