Hi There,
I have a number of questions regarding the correct configurations of the pins to power this IC.
- Clarifying that the 400mA on the VCC pin was just an inrush transient during start up. What is the nominal current into the VCC pin during normal operation?
- If using an external supply for VEXT, should VCCSW be left floating, tied to GND, or tied to VCC?
- If using an external supply for VEXT, should VSW be left floating or tied to GND?
- If using the internal clock only, then should XIN and XOUT be tied to ground or left floating?
Many thanks,
Ross
