TPS51200 - current required for Vin?

Other Parts Discussed in Thread: TPS51200

How much current is required for Vin (3.3V) on the TPS51200?  I only see the requirement for a no load condition in the data sheet.  I know this is not a large number but how should a customer budget for this during normal operation?

Thanks!

    Allen,

    The current actually used by the part and not including the current that merely goes through the part to a load is usually budgeted to be the worst case currents at no load at I_IN, I_LDOin, and I_REFIN - as you have already suspected.  Any current that goes to a load at VO or REFOUT must be added to these respectively.
