Hi Expert,

I see there is a VCC sourcing current limit data on the datasheet. The typical value is 105mA. Could you tell what's the VCC current value for the normal operation condition?

Hi Lenna,

The current limit is 35mA. The actually VCC current for normal operating is basically determined by the MOSFET used:

Qg x Fsw
