DC to DC Boost Chopper

[mufcforever7]

hihi,

can any1 help me with the DC to DC Boost Chopper circuit?

I would like to boost up from 9V battery to output 12V...

Thank you very much for the kind help!

How many milliamps? The M34063 smps IC has a very simple circuit in the datasheet for a boost regulator. It only requires the IC and a few other parts.

[Mr RB]

You will get more help if you provide better information. How many milliamps do you need at 12v? What is the device that will run from 12v? Things like that.

Mr RB,

i would like to use as the supply to drive a 12V dc motor.

 

[blueroomelectronics]

How much current does the 12V motor need? What is its stall current?

hi blueroomelectronics,

my motor just need less than 5amps only or perhaps only mili amps becasue i am just using the normal 12V dc motor only.

i am doing this for my project...

please guide me...

thx u!

What's the part number on the motor? There should be a ratings sticker.
