3 7 v to 12v step up circuit.

And then i connected 12v led to the output then measure current input is 40ma as figure 4. Summing up this project worked surely. Testing dc step up converter circuit using ka34063. Exclusive items from our brands.

Measure current of led is 24ma at voltage 12v. I apply 5v dc regulator from this project to input and measure at the output is 11 50v or about 12v. In this article 3 7v to 5v boost converter circuit is designed with dc dc step up converter me2108 series. 1 offer from 4 93.

Ic me2108 is a step up dc dc converter with low supply current this ic reduces high frequency switching noise and output can be programmed between 2 0v to 7 0v. It requires only three external components to become step up converter. Measure current of the circuit is 100ma at 3 9v. Schematic of 3v to 5v booster circuit at the heart of the circuit is one tiny chip ht7750a which is a pulse frequency modulation pfm step up dc dc converter with high efficiency and low ripple.

Since this circuit is very popular. Apply the led to the output terminal and measure the led voltage. So i tested them on real the universal pcb board. Apply the 3 6v battery or 3 7v mobile batts to the input terminal.

It operate normally till the controller reads 12 2 v it shows low battery symbol 1 then stops. Kangnice boost voltage regulator converter dc 3 3v 3 7v 5v 6v to 12v step up power supply 5 0 out of 5 stars 2. This circuit can be used to power your 5v microcontroller similar circuits from two standard aa cells 1 5v x2.
