Problem is getting a BT adapter that works with the Android Tablet. I take it you can write tablet apps like a program to display the voltages?

34063, 340635, 34063A

I think i can wing it with the parts i have, especially once i read that line from fernando which might help too cause i have so many N channel devices on hand. That allows datasyeet testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously.

So with the parts values I chose it was peaking on the current limit and in sync with the inductor ripple and the internal oscillator. I added a brass angle shim and large sloder blob to cool the PFET which now never gets much warmer than body temp.

The small Tablet computers make an exceptionally nice base for a number of different pieces of test equipment, a multi channel volt meter just one example. Replacement Transformer Started by ncag Today at 7: That would be very cool, especially if it was just the 3463a USB lead. The Tablet load could be represented by a load that changes in value like a lower to higher resistance and then back again depending on mode of operation either strictly running the device or both running and dataeheet or just charging, and if charging what state the battery is in.


Since the efficiency is 93 percent at 1 amp out this should work nicely.

The has two types of regulation; the normal voltage regulation has a fixed on period and fixed frequency, and will skip on periods or cut some on periods in size to maintain voltage out.

Here’s how the board turned out, tidied up a bit dataxheet neat enough to be buried deep in a robot chassis. But thanks anyway and maybe i’ll use something from it.

Media New media New comments Search media. What i’d like to do is use the Android Tablet the same way, even if it means creating new software for the Android environment rather than Windows. The charger automatically selects between 7. It’s basically discontinuous, or very close to it, and quite erratic looking. This language allows quick changes right on the Android Tablet so i can set up different things quite easily.

Also, it has to be be able to put out 1 amp in voltage regulation all the way up to 2 amps ideally with no sign of going into non voltage regulation mode. I’ll have to dig out my parts and build up a breadboard too next. Is your goal to get your smart charger to send comms data to the tablet to 340633a all the charging stats on the tablet screen? The dqtasheet PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1.

12v to 5v DC high efficiency SMPS buck converter using 34063 IC.

It doesnt have that built in and im not sure if it ever will. Inspriation come daasheet ETO member Mr Al who mentioned his interest in a high efficiency darasheet supply to power his Tablet PC during power blackouts etc, see his thread here; http: But you may want to go with Bluetooth if you are interested.


Well, i am aware of how a peak current limit works in regulators but that’s not really the kind of regulation i would need for this project.

I was wondering if you might have some notes on this or if not if you would be interested. Then it slowly adjusts PWM to keep battery voltage at the correct regulation and also limit current during the initial bulk charge to 1.

I started a new thread about this subject a few days ago: That would be nice to see too and i could compare with my notes.

But google Mosfet turnoff circuits. I’ve even considered electrical stimulation of the touch pad itself in a designated area of the screen but that would be exceptionally slow, too slow for my purpose. It does support Bluetooth. What it also does not have is Bluetooth, but since it uses the more current op sys the op sys supports Bluetooth.

It could be the Linux ones work but im not sure yet as i am quite new to this operating system and hardware. Hello MrRB, Thanks for posting that circuit, it looks very promising.
