Click here to register now. I was looking for about 1 amp nominal output current with up to 2 amp capability. This actually reduces the length of the on period.

Hi MrRB, That’s one goal yes, with the overall goal being able to monitor just about any process, and to start with to use the Tablet as a general 34063z test bed for other plug in test equipment starting 34063aa a four channel volt meter.

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. The program board i have does it that way too to regulate the 12v program pulse amplitude.

It is shown for a N-chan Fet, reverse the diode and transistor polarity. It seems hard to get an external Bluetooth device to work too, so im looking for other ways.

It’s basically discontinuous, or very close to it, and quite erratic looking. Thanks for the link, this should help too because i have a lot of good N channel low Rd devices already on hand. This language allows quick changes right on the Android Tablet so i can set up different things quite easily.

Then it slowly adjusts Eatasheet to keep battery voltage at the correct regulation and also limit current during the initial bulk charge to 1. Datasbeet Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Energy conversion efficiency is very high due mainly to the choice of external components used with the cheap SMPS IC.


Hi Mr AL, thanks. 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 datawheet not near to a PC to do actual Android programming Java or whatever.

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. The other regulation occurs from the current limit sense resistor. Forums New posts Search forums.

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?

That would be nice to see too and i could compare with my notes. 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.

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.

Potentiometer Questions Started by norbss Yesterday at Operation is pretty simple; the PIC has 2 ADC channels, and monitors the battery voltage and current sense resistor voltage. I always meant to try datasheet PIC as feedback for datasheet regulation but never got around to it.

The external PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1. Since the efficiency is 93 percent at 1 datasheer out this should work nicely. Oh ok, they also include home made boot strap drivers, which is a nice change. 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.


I started a new thread about this subject a few datashset ago: But i’d like it to be as versatile as the Windows based program panel. 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. Let me know what you think about this if you can. I was thinking of an entire inverted scheme, but this looks interesting too.

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? That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously. 340663a other interfacing options does the tablet have? These are stacked so to get battery voltage it reads the current then subtracts that reading from the voltage to give true battery voltage.

I was wondering if you might have some notes on this or if not if you would be interested. Here’s 3406a the board turned out, tidied up a bit and neat enough to be buried deep in a robot chassis. It does support Datasjeet.
