Selecting low power monolithic boost controller

[makebit]

Hi,
Muggins here agreed to get a PCB done for tomorrow,
But didnt realise how long it would take to find a low power monolithic boost controller IC.
All we need is vin 2v7 to 10V, Vout = 5V, iout = <20mA.

But the ti.com search engine just crashes every time i try and sort by a column.

I know ti.com are the best for this, does anyone know a part number off the top of their head?

for Vout < Vin a regular boost won't do

[makebit]

Thanks, yes, vout will always be > vin....we want "vin_withstand" to be high enough so that sudden vin connection doesnt "LC ring up" and blow the input voltage pin.
So Vin could be 4.3v and sudden, so anything up to 10v input withstand is preferred.

As discussed, the ti.com search engine is crashing, so we are just going through one by one.....and so far, LM27313 is the lowest power with an 800mA switch current limit...but i am sure there is lower than that.
I always used to use a richtek one with a 20ma current limit, but it must now be  obselete.

but if Vin is 10V so is Vout

20mA has been competed out of the market.
