40V / 0.2A / 1A
Vout_max = 22.7V at Vf=3.2V, 2P7S, Headroom V=0.3V
LED Vf=3.2V, If=23mA/46mA(2string), 2P7S
20% inductor tolerance => fsw=500khz : Ipeak = 722.6mA, fsw=1MHz : Ipeak = 541.9mA
20% inductor tolerance => fsw=500khz : Ipeak = 651.9mA, fsw=1MHz : Ipeak = 473.3mA
LED Vf=3.0V, If=20mA/46mA(2string), 2P7S
If you have other LED spec&quantity, recaculate Ipeak And select Power inductor
30% inductor tolerance => fsw=500khz : Ipeak = 774.2mA, fsw=1MHz : Ipeak = 567.7mA
30% inductor tolerance => fsw=500khz : Ipeak = 702.9mA, fsw=1MHz : Ipeak = 498.9mA
You select diode spec : VR > Vout_max, If > LED If(all string current), I_FRM > Inductor Ipeak
