TPS63000DRCR question

Other Parts Discussed in Thread: TPS63000

Just using this buck/boost for the first time.

For some reason, with nearly NO load, the converter is drawing approx. 300 ma (2.5V in) !!

The boost is putting out a nice 3.3V though.  It is oscillating in the 600khz range.

When I remove the boost from my circuit (cuts and jumps) and feed the circuit with 3.3V ... the remaining circuitry draw almost no current (less than 1ma).

The layout seems ok and the schematic is identical to that of the TPS63000DRCR dev board ?!?

Any ideas ?

Bill
