lil help here, please!

is this gonna work?
this is the specs and info on the reg

thank you! i studied art in europe
look at my post#, guess im gonna vape it

Wheres your negative wire from the batt? Looks like you need a cap on the Vin line too. Do you have the data sheet?

Cap on Vout too.

 

[nicotime]

Oops...never mind...duh!!

 

[Sci]

I've got to check out the pdf more, but I'd say no. You need your Input voltage going to the switch(Enable) & the Vin. The way the schematic looks, it won't let anything pass until the switch(Enable) is triggered even though the Vin has a constant source. It says to disable the function, connect Enable to ground, if it's not in uset, connect it to the Input voltage.

i should have the ground (-) going on the atty cuz silvia is a flashlight. do I really need caps on a regulator? the other ones i have going they work just fine without it...

 

[nicotime]

What Sci said..but you need to run a ground wire to the atty and GND pin from the batt. Caps on IN and OUT too.

Dunno...says recommended but never tried it without them??

 

[misterD]

have you been working out? impressive!!
wheres connman?

 

[WillyB]

When the input voltage is a battery (a rather smooth/even supply) I don't think input caps are really needed.

 

[Connman]

Ok I just sent you a pm misterD then checked here again. Where did you get this regulator by the way?
Madvapes don`t carry them anymore. And according to the copper pipe mod made in madvapes that diagram works.

The ground needs to be a mod as mentioned in the text under the diagram.

i was going to say something electrically but connmans new look really got me laughing.hahaha

The trouble I`m seeing is the side of your switch in your diagram with the two wires. The post coming off the the battery should have two one from the battery to switch then continue to pin one. The other switch post should be run to pin 2. And a resistor isn`t shown.

 

[misterD]

so from + batt source i run one wire to switch and one other to Vin. other switch pin goes to EN (control pin?). can it work with no resistor?

I`d want to say no but I can`t say for sure. I know the 4 pin needs it to work. And I`d bet this one as well.

Yes, & it doesn't show a resistor in the wiring diagram. The block diagram of the regulator shows resistors that are built in.

"Enable. This pin allows for on/off control of the regulator. To disable the device, connect to GND. If this function is not in use, connect to Vin."

 

[Connman]

Ok there you go Sci says yes it will. And I don`t know so let me know on the test run. Though I tend to agree with Sci here.

I would for sure wire this up temporarily to test run it first.

I'm just going by what the manufacturers wrote up. Times like this, a breadboard comes in real handy.

[OT]BTW, still haven't put down that eclipse tin.

checked with the voltmeter and the power is always on. good thing is that it lets through below 5V like when i have a single 18650 in. with 3V batts in i get 4.99V... now how do i fix this switch?

Well Hmm what kind of switch you got there misterD? Other then one that`s on all the time it seems. Have you checked it with the meter to be sure it is in the switch itself?

 

[Sci]

The datasheet says to disable this device(is that the whole component or just the disable feature?), hook Enable to ground. Since the schematic really doesn't say where it goes, I wonder if it should be hooked to ground via the switch. Only thing, it would need to be a normally closed switch. Then when you press it, it would open the circuit causing the disable feature to be disabled & the power would flow.
I know what it is... The name of the component is NCP5666.
