I always meant to try a PIC as feedback for voltage regulation but never got around to it. Datasheets, Manuals or Parts.

Hi MrRB, Oh yeah pretty nice! The board above was adapted to now become a high efficiency dahasheet charger for a 6v battery. Oh ok, they also include home made boot strap drivers, which is a nice change. Problem is getting a BT adapter that works with the Android Tablet. The Tablet load could be represented by a load that changes in value like a lower to higher resistance 34063q then back again depending on mode of operation either strictly running xatasheet device or both running and charging or just charging, and if charging what state the battery is in.

It could be the Linux ones work but im not sure yet as i am quite new to this operating system and hardware. It does support Bluetooth. But what it doesnt do is read RS To participate you need to register. Datasheett google Mosfet turnoff circuits.

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.


It went together pretty quick in about an hour, I think it took a couple more to write it up and photos, scan the schematic etc. Here’s how the board turned out, tidied up a bit and neat enough to be buried deep in a robot chassis. 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.

Inspriation come from ETO member Mr Al who mentioned his interest in a high efficiency 5v supply to power his Tablet PC during power blackouts etc, see his thread here; http: Unfortunately, I can’t draw the circuit in my phone and won’T be back home until the 2nd of Jan.

Operation is pretty simple; the PIC has 2 ADC channels, and monitors the battery voltage and current sense resistor voltage. 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. Re the waveform skipping etc, that was xatasheet happening at currents over 0.

From what i have read now some dont work and some do, so it’s a toss up. Energy conversion efficiency is very high due mainly to the choice of external components used with the cheap SMPS IC. This language allows datqsheet changes right on the Android Tablet so i can set up different things quite easily. All the simulations always show at least some deviation from the normal ripple.

Hi MrAL, sorry I don’t have any tablet experience at all, not owning one. What it also does not have is Bluetooth, but since it uses the more current op sys the op sys supports Bluetooth. This actually reduces the length of the on period.


I’ll read it and see what it has to offer then get back here with some comments. But you may want to go with Bluetooth if you are interested. That would be nice to see too and i could compare with my notes.

But thanks datashheet and maybe i’ll use something from it. I started a new thread about this subject a few days ago: Im going to be looking into this more and finally i’ll be building up the circuit.

Potentiometer Questions Started by norbss Yesterday at No way around it. The only problem i am having now is interfacing my circuit to the Tablet because my Tablet doesnt have Bluetooth.

The charger automatically selects between 7. This would be easier to see with a wider time period for 34063aa at the output ripple voltage. I was looking for about 1 amp nominal output current with up to 2 amp capability.

I’ll have to dig out my parts and build up a breadboard too next. Hi MrRB, 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 take it you can write tablet apps like a program to display the voltages? Please note that when i started that thread i thought the BASIC language would somehow handle an RS connection, but apparently it doesnt as i have now read. Forums New posts Search forums.

It seems hard to get an external Bluetooth device to work too, eatasheet im looking for other ways.
