Power supply | Primary side
For a proper operation of the SKYPER
®
12 PV driver core, a power supply of at least 15W/1A shall be
connected to the driver’s power supply pins. During power-up of the driver turn-on signals should not be
applied to the driver’s inputs TOP_IN/BOT_IN, otherwise the driver will not leave the error state.
Please note, when controlling power semiconductor modules with a gate charge ≥ 2.5 µC external boost
capacitors (C
BST
) are recommended to support the supply voltage on the primary side. Dimensioning of
such boost capacitors shall be done according to chapter 4.11.
