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. Energy conversion efficiency is very high due mainly to the choice of external components used with the cheap SMPS IC. datasheeet

That would be very eatasheet, especially if it was just the one USB lead. Hi MrRB, Oh yeah pretty nice! I take it you can write tablet apps like a program to display the voltages?

You might be able to get similar specs in something convenient like a TO pack but since it doesn’t need heatsinking you could use any package really. No way around it. It’s basically discontinuous, or very close to it, and quite erratic looking.

I always meant to try a PIC as feedback for voltage regulation but never got around to it. What other interfacing options does the tablet datawheet

What it also does not have is Bluetooth, but since it uses the more current op sys the op sys supports Bluetooth. Datasheeh, I can’t draw the circuit in my phone and won’T be back home until the 2nd of 3406a. Then it slowly adjusts PWM to keep battery voltage at the correct regulation and also limit current during the initial bulk charge to 1. The external PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1.

Right now i have constructed quite a while back actually a four channel ‘meter’ that can measure voltages and with some simple interfaces can measure current too. It could be the Linux ones work but im not sure yet as i am quite new to this operating system and hardware. Thanks for the link, this should help too because i have a lot of good N channel low Rd devices already on hand.

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: Problem is getting a BT adapter that works with the Android Tablet.

Is your goal to get your smart charger to send comms data to the tablet to display all the charging stats on the tablet screen? It doesnt have that built in and im not sure if it ever will. I’ll read it and see what it has to offer then get back here with some comments. I added a brass angle shim and large sloder blob to cool the PFET which now never gets much warmer than body temp.

The other regulation occurs from the current limit sense resistor. Just an update for MrAl, re an earlier conversation where I was going to build a 6v 10Ah sealed lead acid battery charger for a robot project. But i’d like it to be as versatile as the Datasheft based program panel. The board above was adapted to now become a high efficiency smart charger for a 6v battery.

Hello MrRB, Thanks for posting that circuit, it looks very promising. To Fernando; thanks 34063q pointing out datzsheet TI appnote on gat edriving, I downloaded a copy. Here’s how the board turned out, tidied up a bit and neat enough to be buried deep in a robot chassis. To get this effect you need the current limit set to datasheeet 1. 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.

All the simulations always show at least some deviation from the normal ripple. The Tablet load could be represented 34063z 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 ratasheet both running and charging or just charging, and if charging what state the battery is in.

Oh ok, they also include home made boot strap drivers, 34063 is a nice change. Saves a voltage regulator i guess As you recall my original question was for a regulator for use with a Tablet computer, well on a related note, have you tried interfacing with a Tablet computer yet?

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

Let me elaborate just a little. 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. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

It went together pretty quick in about an hour, I think datashfet took a couple more to write it up and photos, scan dwtasheet schematic etc.

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. Media New media New comments Search media.

Also, it has to be be able to put out 1 amp in voltage regulation all the way datasheft to 2 amps ideally with no sign of going into non voltage regulation mode.

Forums New posts Search forums. That would be nice to see too and i could compare with my notes. That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells datazheet.

Articles Top Articles Search resources. 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. 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. The reason i bring this up in this thread is because im doing all this for a Tablet computer anyway, and also that if you havent used one for your test equipment you may be interested in looking into that.

So could you do a quick scope shot of this datasheef in voltage regulation? Found some P channel devices, price range 1.
