LD5520 Datasheet | Leadtrend

05/17/2016 Quasi-Resonant PWM Controller with Frequency Swapping and Integrated Protections REV: 00 General Description The LD5520 is built with several functions, protection and EMI-improved solution in a tiny package. It takes less ponents counts or circuit space, especially ideal for those total solutions of low cost. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope pensation. It also Features more protections like OLP (Over Load Protection), FB pin OVP (FB pin Over Voltage Protection) and OVP (Over Voltage Protection) to prevent circuit damage occurred under abnormal...
