For more on the history of switching supplies: Media New media New comments Search media. From what i have read now some dont work and some do, so it’s a toss up.

Selling HTC, HTC, HTC with HTC, HTC, HTC Datasheet PDF of these parts.

If I read the available information correctly, it was Motorola now OnSemi who first 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. For a htcc experience, please enable JavaScript in your browser before proceeding.

SZ Goldensun Electronics Co. Then it slowly adjusts PWM to keep battery voltage at the correct regulation and also limit current during the initial bulk charge to 1.

You might 3406 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.

The is used by the millions in ultracheap Chinese 12V-to-5V converters. Post as a guest Name. Contact Details Assessed Supplier.

Im going to be looking into this more and finally i’ll be building up the circuit. By continuing to use this site, you are consenting to our use of cookies. Home Questions Tags Users Unanswered.

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. That’s basically good when we have a constant load. A Aug 6 ’13 at Wuhan Part Rescue Technology Co. That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously.


These are stacked so to get battery voltage it reads the current then subtracts that reading from the voltage to give true battery voltage.

It’s basically discontinuous, or very close to it, and quite erratic looking. 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. But google Mosfet turnoff circuits. I was thinking of an entire inverted scheme, but this looks interesting too.

I’m not sure who cloned who. Compared to more modern switchers its performance is rather lousy, but for these manufacturers only price counts. Click here to register now.

I take it you can write tablet apps like a program to display the voltages? Looking at all these cross-references knock offs?! It went together pretty quick in about an hour, I think it took a couple more to write it up and photos, scan the schematic etc.

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. So could you do a quick scope shot of this thing in voltage regulation?

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

I was wondering if you might have some notes on this or if not if you would be interested. To get this effect you need the current limit set to about 1. Shenzhen Hongxingfan Electronic Tech Co. When was it introduced?


Energy conversion efficiency is very high due mainly to the choice of external components used with the cheap SMPS IC. 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. But i’d 340633 it to be as versatile as the Windows based program panel. 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.

I always meant to btc a PIC as feedback for voltage regulation but never got around to it. 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.

It is shown for a N-chan Fet, reverse the diode and transistor polarity. Hi MrRB, Oh yeah pretty nice!

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

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. This actually reduces the length of the on period. 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. Both the LM and the MC are still available!
