Really my question is would I need to put another diode at of the end of each V+ booster circuit before the parallel connection or will the circuit work without this? Are you in search of a reliable and high performance but simple 5v to 12v boost converter circuit? So here, in this comprehensive post, we have provided an insight of DC to DC Boost Converter & Modules, its schematic circuits, datasheet, pinout, features, and intended applications. 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.) 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. 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.

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. 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. Below schematic is implemented using readily available Lm2577-ADJboost converter IC having adjustable output feature: In this post we will be avoiding using the old school method and only focus on boost converters with simple ICs. Earlier methods or you can say older methods used transistors as a switching device externally and lots of components were required to implement it making it complex. That is the reason to go with ICs and modules. Also it will save a lot of time to center your attention towards the actual functioning of the project rather than the power supply.
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? LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. i think the gelid is just an fancy Arduino controller with the fan and rgb ports hooked to it. but i could be wrong

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. Is this possible with the help of some generic parts (and not with the help of some expensive transformer, etc.)? 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: I’m trying to develop a project for TEG’s where I’m gathering electrical energy from various sources. 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).
Meeting power demands in modern day electronics is quite a challenge and there are times where we will not be able to supply sufficient voltage for our circuits. In that case we need to go for DC to DC boost converter circuits like these to step up the incoming voltage to a certain usable level. These kinds of step up converter circuits will be useful in Solar powered projects, Lighting systems, Battery powered projects and so. MT3608:
