ARGB Airgoo Computer Fan Controller Commander - Speed Adjustable 3-pin or 4-pin fan - Include Strip PC Software So I got a converter, the deepcool. Thing is, it only converts 1 5v3pins into 12v for the motherboard, but I have multiple ARGB components shipped already (RGB Fan hub, RGB HSF, RGB m.2 heatsink, RGB Gpu support).

After the MOSFET is turned off, the magnetic field of the Inductor turns in to voltage spike and it goes through the Schottky diode. Hence this voltage spike will be exhibited as output in the circuit. As there is a capacitor in the output, it charges in every cycle of oscillation and keeps the voltage constant. In this voltage booster circuit components are used to boost 5v to 12v. Above all for MT3608 to start working, the EN pin should be tied to high. If you want to turn on and off the output with an external circuit you can use this pin. This circuit is capable of delivering 2A current to the Load. ADJUSTABLE OUTPUT VOLTAGE: With the voltage boost converter module with IC Lm2577-ADJ, you can draw 12V @800mA stable DC voltage output at a wide range of input voltage levels from 3V to 40V. The LM2577 is designed with an 3.0A NPN switch, which is also equipped with a thermal and current limiting protection circuit. regulation to make sure the output stays at 12V as long as the load consumption stays within the specs.

isolation if you plan to power a device which is somehow connected to the mains as well. That way you wont fry your computer if your computer and the device are not on the same phase. If you want your 5V ARGB devices to act like 5V ARGB devices (multiple colors at the same time) you will need an ARGB signal coming from somewhere. Many controllers can get their ARGB signals from USB 2.0 headers and third party software instead of a dedicated header and motherboard software (Such as Corsair or NZXT, but I dont know of any brands that work with standard ARGB equipment off the top of my head.) I am trying to design a tiny PCB to repair some equipement (hence the tiny PCB, it HAS to fit in the existing housing), and I need to put a 5V to 12V booster to power a 2W stepper motor (3.5V*0.6A) through a A4988 stepper driver (Althrough, typically, the draw is only around 1.5W). This circuit is similar to the above except output voltage in the circuit can be adjusted. As I already mentioned that output voltage is set by means of Voltage fed into the FB pin of MT3608. Here I have replaced the resistor R1 with Potentiometer PR1. As the resistance of POT changes the voltage in to the FB pin changes which in turn will change the output voltage accordingly.

You are using a 22µH inductor, which is at the high end of what the datasheet says. I started my design by copy/paste of an existing easyEda project which was with a 4.7µH… what is the difference between the 2 choices? what would you recomend I use for my design? Would you have a part number to suggest?Correct. A 5v ARGB device (fan, LED strip, etc) plugged into a controller that only receives an 12V RGB and converts it to a 5V signal can ONLY display that single color. It is not able to display multiple colors like a normal ARGB connected device would. The LT1173 consumes just 110µA supply current at standby, making it ideal for applications where low quiescent current is important. The device can deliver 5V at 80mA from a 3V input in step-up mode or 5V at 200mA from a 12V input in step-down mode.
