DER-903 Design Bug
I'm working a project that using InnoSwitch3-EP INN3279C-H215 IC. So DER-903 reference desing good resources for me.
When I look the schematic (Figure-3, Page-7), i see that T1 transformer pins is wrong. No:4 pin is duplicated. Is it typo mistake or another reason for this numbering.
Also Page-28 Input HF Common Mode Choke Specifications 250 µH Common Mode Choke marked as (L3). But in the schematic L3 component doesn't exists.
Can you clarify these items please?
