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. It doesnt have that built in and im not sure datashheet it ever will.
Let me elaborate just a little. This would be easier to see with a wider time period for looking at the output ripple voltage. But i’d like it to be as versatile as the Windows based program panel. This actually reduces the length of the on period.
Energy conversion efficiency is very high due mainly to the choice of external components used with daatasheet cheap SMPS IC.

Oh ok, they also include home made boot strap drivers, which is a nice change. This language allows quick changes right on the Android Tablet so i can set up different things quite easily. Welcome to our site!
The charger automatically selects between 7. I added a brass angle shim and large sloder blob to cool the PFET which now never gets much warmer than body temp. No way around it. Datasheets, Manuals or Parts. I think i can wing it with the parts i have, datasbeet once i read that line from fernando which might help too cause i have so many N channel devices on hand.
I was thinking of an entire inverted scheme, but this looks interesting too. Forums New posts Search forums. 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.
Since satasheet efficiency is 93 percent at 1 amp out this should work nicely.

To Fernando; thanks for pointing out the TI appnote on gat edriving, I downloaded a copy. The external PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1. The board above was adapted to now become a high efficiency smart charger for a 6v battery.
Hi MrAL, sorry I don’t have any tablet experience at all, dataheet owning one. 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. You must log in or register to reply here. 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.
Adtasheet is getting a BT adapter that works with the Android Tablet. The program board i have does it that way too to regulate the 12v program pulse amplitude.

I’ll read it and see what it has to offer then get back here with some comments. Replacement Transformer Started by ncag Today at 7: The has two types datashdet 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.
But you may want to go with Bluetooth if you are interested. To get this effect you need the current limit set to about 1. 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 is shown for a N-chan Fet, reverse the diode and transistor polarity. Click here to register now.
I started a new thread about this subject datashest few days ago: 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. Let me know what you think about this if you can. 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?
