a no-brainer link to the chip I can use, delivered to me in the UK at a reasonable cost.

Pololu has several boards. For battery operation, I like this one:

https://www.pololu.com/product/2122

But for more than 12V input, there are step down boards that are cheaper and more logical in that application.

They have UK distributors, so you could have it tomorrow.

I have no affiliation with Pololu, but have used their products and the quality has been good for the price.

At this point I'm happy to accept that I'm a moron in exchange for a no-brainer link to the chip I can use, delivered to me in the UK at a reasonable cost.

eBay can be worth a try, for instance: http://www.ebay.com/itm/TEXAS-INSTRUMENTS-TPS61200DRCT-CONVERTER-BOOST-SYNCH-1-5A-/271779733959?pt=LH_DefaultDomain_3&hash=item3f4755a1c7
A lot of chips are sold on eBay from China with free shipping, but alas - not this one. Such shipments from China tend to arrive in my mailbox in Norway in around two weeks.

Arnie thanks for making time to reply to me...

... but I've tried EBay and failed and frankly so have you because this link is completely unhelpful, in that (1) this is 5.5V and I need 3.3V (2) it's a BOOST and I need a BUCK or BUCK & BOOST (3) it's surface mount - which I can't do and (4) it's TINY - 6 pins on a 3mm side is totally beyond my ability to do anything except swallow it by accident.

I do appreciate your time but it's pretty frustrating to be sent a link which is so totally NOT what I am looking for.

I was under the impression that the main problem with this chip was shipping cost; sorry for having misunderstood that.
(And 5,5V is a max rating.)

- Sun Feb 22, 2015 8:00 am #10398 Are there any one board solutions to the battery power sensor?

Ideally, it would:

1. Charge the lipo battery from a usb port and an attached small solar panel if connected.
2. Have a timer that would kick it on after a preset time (e.g., DS2417 like).
3. I2c, one wire type interface to set timer and turn it off.
4. Provides regulated power from battery.

There should be something like this available but if so I can't find it.
