LM27313: What is the ratio relationship between Vin and FB in LM27313 boost chip?

Part Number: LM27313

Hello Team,

What is the ratio relationship between Vin and FB in LM27313 boost chip?

I have a 12V boost 24V power supply project on my side, currently I only see one in the specification book Δ VFB/ Δ The relationship between VINs, and the resistance value of R1 is determined by the formula R1 = R2 x ((VOUT / VFB)1). I am not sure how to set Vfb at this time.

There is no recommendation for L1 inductance selection, the load current is about 600mA.

Best Regards,

James
