You can actually build this with op-amps/555s/resistors/diodes and a decent MOSFET (n channel) and if you are not that bothered about super high effciency then a NPN can replace the MOSFET. ps. the hubs and controller are connected directly to the sata PSU pins, so I'm assuming there would be no problem with the amperage etc.

As I said, not an electronic engineer, hence my beginer questions… As a general rule, it seems that each IC is asking for input/decoupeling capacitor on 5V/VCC, is it ok to not put all these caps and reduce component load? The Deepcool attaches to your 12v 4 pin header for RGB and then allows you to connect a ARGB device, you'll need to split off the ARGB port to add additional ARGB parts though. It only really converts it though so your ARGB fans become like RGB devices. Each individual LED on the ARGB cannot be controlled like with ARGB. fans sould be find you will need a splitopr thow(just dont do more then 3) ya it will make your argb 5v dum like 12v. You don't have permission to access "http://www.mouser.com/c/power/dc-dc-converters/isolated-dc-dc-converters/?" on this server.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). If you’re looking to power your micro-controller based project or its associated peripherals, we would highly recommend procuring a DC to DC Step-Up module. Not only are they designed to occupy minimal space, but also many of these modules have adjustable output voltages, making them ideal for a wide range of applications. This USB 5v to 12v converter is most useful for powering up the WiFi router and decorative LED strip.

The output source impedances are typically 150Ω, providing useful output currents up to 10mA. The low quiescent current and high efficiency make this device suitable for a variety of applications that need both positive and negative voltages generated from a single supply. The intended output can also be drawn out using a fixed output 12v switching IC Lm2677-12 which comes under the lm2577 series step-up voltage regulator, image for schematic circuit is shown below: CPUi7-4790k MotherboardGigabyte Z97N-WIFI RAMG.Skill Sniper DDR3 1866mhz GPUEVGA GTX1080Ti FTW3 CaseCorsair 380T

ARGB Airgoo Computer Fan Controller Commander - Speed Adjustable 3-pin or 4-pin fan - Include Strip PC Software The LT1173 is a versatile micropower DC-DC converter. The device requires only three external components to deliver a fixed output of 5V or 12V. Supply voltage ranges from 2.0V to 12V in step-up mode and to 30V in step-down mode. The LT1173 functions equally well in step-up, step-down or inverting applications. A hub only adds more headers if you have a motherboard with 1 3-pin 5v header. My motherboard has 0 3-pin 5v headers. i think the gelid is just an fancy Arduino controller with the fan and rgb ports hooked to it. but i could be wrong Depending on what you plan to power with that, you might consider regulation and electrical isolation.ADD-RGB equipment can be compatible with 12V RGB motherboard via the convertor, to achieve synchronous lighting compatibility. 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. 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). 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. I’m trying to develop a project for TEG’s where I’m gathering electrical energy from various sources.

Below schematic is implemented using variable output high efficiency IC MT3608. A compact and small form factor of this module/IC makes it possible to install this IC in size and weight imperative devices. Also works on very low current drawing loads contrary to its competitors. buy a rgb hub that fits your rgb. if you have a port you could likely add more fans to it, until the power cant reach the rgb so maybe max 2-3 fans? not sure, just something to test. else 3 or 4 pin/volt difference to each other, no thanks? 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: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.) Simillary to my question in 1), the 5V rail has 0.1µ, 4.7µ and 22µF capacitor, can I do the economy of at least one of these (once again, PCB space reducing)? This design has a 22µF “output” capacitor. But I already have a 100µF capacitor as an “entry” to the A4988 stepper. PCB space is VERY limited for me. Can I just use the 100µF and drop the 22? So I would only be able to use static colors? Also, let me know if that controller kit works out for you. like that being a way to make it work, no? and what? you don't need that on the motherboard, only USB pins?
