Below schematic is implemented using readily available Lm2577-ADJboost converter IC having adjustable output feature: 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. The USB 5v to 12v dc dc converter is a compact portable electronic device that is designed to boost up 5 volts from the USB port to 12 volts efficiently. As we know that 5 volt USB supply is available everywhere but what if we require a 12 volt power supply for any application then this device comes to the aid.

I have shared my project on easyEda at: https://easyeda.com/editor#project_id=9220fa26c27845ae8d1bbd93b3a543d9 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. 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. Depending on what you plan to power with that, you might consider regulation and electrical isolation.For an input of 5v, the output of this IC’s can deliver a maximum of 800mA at 88% efficiency. For higher output current you have to increase the input voltage above 5 Volts. 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. 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.

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?ARGB Airgoo Computer Fan Controller Commander - Speed Adjustable 3-pin or 4-pin fan - Include Strip PC Software regulation to make sure the output stays at 12V as long as the load consumption stays within the specs. 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. It depends on the input voltage and current, the amount of the maximum stable output current is produced. These DC-DC boost converter modules operate at the frequency ≥1.2MHz, the typical efficiency is 93% subjected to the withdrawn load current.

As this is an Adjustable version of step up voltage regulator/ boost converter, we have to select the value of output voltage (here 12v) which is directly dependent on voltage determining resistors (here R5 and R6).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 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: In-built oscillator with 52KHz frequency with power conversion efficiency up to 92%, higher the output voltage higher is the efficiency.

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: 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: Soft start function (reduces current ripple and spikes during start-up, by limiting the initial current flow). 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 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? 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)? 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.) 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.
