TPS54120: much smaller package than TPS54120

hi all

  now my customer wants a device :  300mA DCDC (5V --> 3.3V)  +100mA LDO(3.3V --->1.8V)

and I find TPS54120 is OK but the package is too large. Do we have much smaller package than TPS54120.

because they have another choice the competitor is only 1.2mm x 1.6mm.

thanks a lot
