It is shown for a N-chan Fet, reverse the diode and transistor polarity. Re the waveform skipping etc, that was not happening at currents over 0. Hi MrRB, Oh yeah pretty nice!

It’s basically discontinuous, or very close to it, and quite erratic looking. 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. Media New media New comments Search media. That would be very cool, especially if it was just the one USB lead. It seems hard to get an external Bluetooth device to work too, so im looking for other ways. To Fernando; thanks for pointing out the TI appnote on gat edriving, I downloaded a copy.

Hi MrAL, sorry I don’t have any tablet experience at all, not owning one. 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.

The circuit for this buck converter is nothing original, basically it is the circuit from the IC datasheet, and all I did was to use an external PFET instead of the external PNP transistor shown in the datasheet.

But also it would be nice to be able to use that BASIC language as that would give me the ability to change the program even if im not near to a PC to do actual Android programming Java or whatever. Replacing a 4 pin leaded inductor with a dtasheet pin Started by gkmaia Yesterday at I take it you can write tablet apps like a program to display the voltages? Welcome to our site!

Unfortunately, I can’t draw the circuit in my phone and won’T be back home until the 2nd of Jan. Please note that when i started that datashwet i thought the BASIC language would somehow handle an RS connection, but apparently it doesnt as i have now read.

Saves a voltage regulator i guess As you recall my original question was datasheer a regulator for use with a Tablet computer, well on a related note, have you tried interfacing with a Tablet computer yet? This language allows quick changes right on the Android Tablet so i can set up different things quite easily.

To participate you need to register. I was looking for about 1 amp nominal output current with up to 2 amp capability. Ddatasheet 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.

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.

Basically it used the current limit peaks to shorten the osc period from 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 dataseet equipment you may be interested in looking into that.

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

The external PFET allows currents up to a few datsheet at good efficiency, however I have used hard current limiting at 1. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

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

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. 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. BTW, when you look at the output waveshape for a while do you see any quick jumps once in a while?

Forums New posts Search forums. 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. Let me know what you think about this if you can. The charger automatically selects between 7. That allows easy testing of battery cells of just about any type 34063z versatile set up capabilities which allows testing of four cells simultaneously.

Hello MrRB, Daatsheet for posting that circuit, it looks very promising.
