... Iout = Vfb/RA where RA is the parallel combination of Ra and any of the resistors Rb Rd. If Ra, Rb, Rc and Rd are used then RA = 1/(1/Ra + 1/Rb + 1/Rc + 1/Rd) Standard SP7600EB Evaluation Board Example: Iout = Vfb/RA = 200mV/0.22ohm = 1A 3) Dimming The SP7600 can be pulse width modulated using a signal applied to the DIM post. The DIM signal connects to the VFB pin through a 1N4148 diode and will shutdown the SP7600 when DIM = H and turn- on the SP7600 when DIM = L ...
