I have a project:
Uin=230Vac (185Vac-265Vac) Uled=64V (60V-72V) Irmsled = 150mA, Ipkled = 230mA (maksimum led peak current).
I want to rebuild a devboard DER328. The PIexpert calculate the transformer (inductor) for my input data. The problem is with peak current which is flown by LED. I found parameter:
Peak Drain current at maximum input voltage
And I wonder if this current will be the same what i'm looking for in PIexpert? Is it possible to put this parameter like peak current on the LED inside calculator sheet for Buck converter (Linkswitch-PL). I want to buy trafo with enough high inductance to reduce ripple and peak current. The PIexpert calculator don't give a possibility to change a trafor's inductance and reduce peak current. Tell me, how can I calculate the inductance of transformer if I want to reduce the peak curren on the LED to 340mA (max).
With best regards.
