Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. 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. Shenzhen Winsome Electronic Technology Co. On thing that confuses me in the MC datasheet is why is there a uA78S40 mentioned there as well.
By the way, I incorrectly stated the uA78S40 and MC share the same ON datasheet; that’s not actually the case, but they share the same appnote: 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.
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.
Hmm, if you want to use bluetooth for data interfacing to the tablet there are lots of cheap bluetooth modules on ytc, just watch out as some are just the “module” but need a carrier PCB which means you need to make a PCB, some are a fraction more expensive but have the carrier PCB included togther with the module.
This actually reduces the length of the on period.
Basically it used the current limit peaks to shorten the osc period from Welcome to our site! 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. Oh ok, they also include home made boot strap drivers, which is a nice change. That would be nice to see too and i could compare with my notes.
12v to 5v DC high efficiency SMPS buck converter using 34063 IC.

BTW, when you look at the output waveshape for a while do you see any quick jumps once in a while? I couldn’t find any earlier sources, httc I don’t have any early data books by Motorola on my shelves. Hi MrRB, Oh yeah pretty nice! The external PFET allows currents up to a few amps at good efficiency, however I have used hard current limiting at 1. I take it you can write tablet apps like a program to display the voltages?
So could you do a quick scope shot of this thing in voltage regulation?

It seems hard to get an external Bluetooth device to work too, so im looking for other ways. Tut 3, 1 15 We have a first-edition copy where I work 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.
Unfortunately, I can’t draw the circuit in my phone and won’T be back home until the 2nd of Jan. I always meant to try a PIC as feedback for voltage regulation but never got around to it. Search Related to “htc ic”: The is used by the millions in ultracheap Chinese 12V-to-5V converters. It does support Bluetooth.

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. My first switching regulator circuit was around using an LM National Semiconductor which could be used as a linear or a switching regulator. Looking at all these cross-references knock offs?!
