LD5520 controller equivalent, quasi-resonant pwm controller.
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 a.
The LD5520 is built with several functions, protection and EMI-improved solution in a tiny package. It takes less components counts or circuit space, especially ideal for those total solutions of low cost.
The implemented functions include low startu.
