LP5024: Maximum drop

Prodigy 160 points

Part Number: LP5024

I have designed in the LP5024 into a product and have it in testing.  I would understand the datasheet to show a minimum output voltage at 10ma to be around 0.250V.

I have operated everything including the LED's from a 3.3 supply, and find that the maximum drive voltage I can get into LED's is around 2.4V, which isn't saturating the LED at all.  The Blue LED is barely visible, I would estimate maybe 1-2ma ?  This would mean the open collector output is around 0.9V.

I am sending a config starting at address 0 of 0x40,0x3C,0x00,0xFF and driving individual led's with 0xFF starting at address 0x0F

Have I misunderstood the datasheet somewhere?
