According to My Data Book, The 330 uH produces an output of "5 Volts at 1 Amp". Thats what you want, I Believe.
Typically A Higher Inductance Lower Frequency and results in Poorer Efficiency. Problem With Higher Frequencies is the Need for Faster Diodes.
Every Change in Parts has its Tradeoffs.
I'm on Slow Internet, so doing searching isn't my thing.
Most cases, I use Step up, Not Step down, SoI don't have a Specific Chip in mind.
Phone Texas Instruments at 1-800-336-5236 (My Favourite)
or Motorola at 1-800-635-8291 (Not Sure if this is a Current Number)
If you give them your requirements, they can help you.
Texas Instruments is also Extremely Helpful for Free Samples.
Motorola (On Semiconductor) also somewhat helpful for samples.
One Chip that I did use was an LT1271, but its rated at 4 Amps. It Worked VERY GOOD for both boost and Reduction. But NOT CHEAP.
