Ofer,
Thanks for posting. 3.3V is under the UVLO threshold of 3.7V which means both FETs will be held low and the device will not switch. As such, we strongly recommend keeping Vdd from 4.5 to 5.5V as indicated in the recommended operating conditions table.

Hopefully this answers your question but let me know if there is anything else I can help you with.
