I’m trying to get an idea when some of the classic switching controller ICs were introduced because it marks the point when switchers started to become ubiquitous. Contact Details Assessed Supplier. Forums New posts Search forums. I added a brass angle shim and large sloder blob to cool the PFET which now never htx much warmer than body temp.
Oh ok, that’s an app note about gate drivers I thought it was an gtc note that pertained directly to that chip. 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. 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 purpose test bed for other plug in test equipment starting with 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 ht going into non voltage regulation mode. 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. The reason i bring this up in this thread is because btc 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.

Hi MrAL, sorry I don’t have any tablet experience at all, not owning one. Hi Mr AL, thanks. Washing machine trip the breaker Started by sew Today at 1: Compared to more hhc switchers its performance is rather lousy, but for these manufacturers only price counts.
It seems hard to get an external Bluetooth device to work too, so utc looking for other ways. 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: With efficiency like that it 43063 well worth looking into for this kind of project.
12v to 5v DC high efficiency SMPS buck converter using 34063 IC.
Shenzhen Winsome Electronic Technology Co. But i’d like it to be as versatile as the Windows based program panel. This language allows quick changes right on the Android Tablet so i can set up different things quite easily. But google Mosfet turnoff circuits.

Personally I would prefer that to any RF comms as it htcc be higher datarate, simpler and probabl more reliable. The is used by the millions in ultracheap Chinese 12V-to-5V converters. Let me elaborate just a little. Htca Supplier Supplier. The fig13 example should be workable fine for the PFET, it just needs to be inverted and then driven from the junction between the two resistors.
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. I was thinking of an entire inverted scheme, but this looks interesting too.
What it 3063 does not have is Bluetooth, but since it uses the more current op sys the op sys supports Bluetooth.
If I read the available information correctly, it was Motorola now OnSemi who htv made this part, and it was or is also available from competitors such as Sipex, TI, ST, Fairchild and some smaller ones I’ve never heard before.
Hi MrRB, Oh yeah pretty nice! The Tablet load could be represented by 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 or both running and charging or just charging, and if charging what state the battery is in.
That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously.
