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.

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. 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). 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. 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?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 These DC-DC boost converter modules operate at the frequency ≥1.2MHz, the typical efficiency is 93% subjected to the withdrawn load current.

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

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. I have shared my project on easyEda at: https://easyeda.com/editor#project_id=9220fa26c27845ae8d1bbd93b3a543d9 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: 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? Depending on what you plan to power with that, you might consider regulation and electrical isolation.Below schematic is implemented using readily available Lm2577-ADJboost converter IC having adjustable output feature: 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. 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: 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.) regulation to make sure the output stays at 12V as long as the load consumption stays within the specs.

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. 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: This USB 5v to 12v converter is most useful for powering up the WiFi router and decorative LED strip. 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).
Bad Move, Microsoft...
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.
