For schematic design of LM3409, such as PDF document design, if the input is 24V and the output is 5V, how should the corresponding parameters be designed? Does VTURN-ON need to be configured?

Hi Songhao,

Please first set up your design specification - like Vin, Vou, frequency, Iled and so on, then follow the design steps in this application note.
The VTURN-ON depends on your application, you can change it accordingly.

Many thanks!

BR,

Hailee.
