Question 1

if I use 12v-7amp battery for input I want 21v - 7 to 9Amp at the output end I know voltage will step -upbut whats about current??

Accepted Answer

I like to think that things are simple, we complicate them to waste time.Think of the simple, a converter with 100% efficiency (this does not exist) if entering 50 watts will leave 50 wattsSimply multiply the voltage and current in and subtract the losses and you will have the result of the output, without forgetting the limits of the circuit

Question 2

So this will regulate voltage? Say I have batteries that can go from 2.6-4.3, will it only boost it by say 150% or will it regulate it so it is always a constant 5v? Thank you and sorry if this sounds confusing!

Accepted Answer

Itwill regulate the output to whatever you have it set to (using the potentiometer) regardless of the input. Let\'s say you set it to 5V out, no matter what voltage goes in it even very fluctuating (like solar pannels or
                                                                                                                    your 2.6- 4.3v batteries) it will automatically regulate the output to a constant 5V. This board can also both buck or boost voltage depending on your needs.

Question 3

Does this have an enable (EN) port?

Accepted Answer

yes

Question 4

is this buck controller's negative input and output common to each other? looking at photo it seems quite possible. please advise.

Accepted Answer

Yes, negative input and output common to each other

Question 5

i need it to make 13.2volts from a car battery which varies from 12.4-14.2volts depending on the car engine RPM/not running etc. can this switch fine than?

Accepted Answer

Yes,by default, but it depends on the magnitude of the load current. You cannot exceed the specified maximum load current, as this will break the voltage and damage the device!

Question 6

very strange behavior if I want to set 5V output then if voltage input goes below 3.6V the output voltage suddenly goes up and very unstable ?! 3.5V input = variable not steady 5.5-7.5V output, 3.4V input = 10V output, with 3.3V input = 8.5V ouput, 3.2V input = 6.4V output, 3.1V input = 4.5V output, 3.0V input = 3.6V ouput, 2.9V input = 2.95V output, 2.8V input = only 0.5V output , all done with a load of only 200mA

Accepted Answer

Part of my review text with photos. The output voltage remained constant even with extreme variation in the input voltage, below 5v is too extreme, without load or with varying loads, in multimeters aneng and hikari the voltage remained stable,
                                                                                                                    varying only at the voltage input, according to load.

Question 7

Q: is this buck controller's negative input and output common to each other? looking at photo it is. can someone who has used this please confirm

Accepted Answer

Yes, negative input and output common to each other

Question 8

can we make a lab bench power supply with this input=12v_1Awhat will be maximum output

Accepted Answer

Coolinglimits the outputpower, power-in x 94%= power-out, max 35v-300mA for 12V-1A

Question 9

My input is 1.5 V and I want 5 or 12 volt.will it work for me?if not then kindly suggust me some good device. thanks

Accepted Answer

InputRange: 3.8V - 32V.

Question 10

Output current at 5v?

Accepted Answer

Ok,I have no clue what the repies below have been smoking...You can chose the output VOLTAGE to whatever you like from 1.25V - 35V as long as you have an input ANYWHERE BETWEEN 3.8V - 32V.Example: IN-3.8v Out-35v \ IN-8.2v
                                                                                                                    Out-16.3v \ IN-32v Out-1.25v.It is a buck AND boost converter and it doesn't care if the input voltage is fluctuating, the output should remain stable in real time no matter what you set it to.
