on video Voltage Boost converter circuit 3.7V to 12V


 Looking for the 3.7v to 12v boost converter circuit? In this article, we’ll discuss a few of these, using a high-efficiency DC to DC step-up converter IC. These step-up DC to DC boost converters are generally available as a module on sale online.

There are many to choose from, for this post we will focus on the boost converter module based on the popular DC- DC switching regulator IC.


It is suggested to buy a DC to DC Step-Up module for just a power supply needed in a project around a microcontroller or to power the peripherals. The reason for this is that some modules have adjustable output voltages that could be useful in various situations. Also, it is designed in a compact space.


The information on this page would be very useful if you are planning a project involving buck converters/ power supply circuits.


Keep reading, as in this post you’ll walk through the introduction and circuitry of DC to DC Boost Converter & Modules, also covering the datasheet, pinout, features, and intended applications.


Let’s get started.

So we can implement 3.7v to 12v boost converter circuit using :LM2577, MT3608, XL6009, and so on


 


3.7v to 12v Boost Converter circuit using IC LM2577

With the voltage boost converter module using IC Lm2577-ADJ, you can achieve 12V stable DC voltage output at a wide range of input voltage levels as low as 3V and up to 40V. The LM2577 is designed with an 3.0A NPN switch, also combined with a protection circuit consisting of current limiting and thermal limiting.


Consequently, this programmable IC must be configured by adjusting the feedback voltage, which is determined by changing R5 and R6. In order to provide the feedback voltage, a voltage divider circuit is incorporated. These DC-DC boost converter modules operate at the frequency 48-53KHz.

Above 3.7v to 12v boost converter circuit is implemented using variable output IC Lm2577-ADJ.

This can be implemented using a fixed output 12v switching IC Lm2677T-12 which comes under the lm2577 series step-up voltage regulator.


Components required:

IC Lm2577-ADJ

Inductor L3≥100uH

Switching diode (Schottky diode) D3=IN5821

Capacitor: Cout≥680uF, Cin=0.1uF, Comp=0.33uF, R7=2.2kΩ

R6 = 2.0kΩ

R5 = 17.4kΩ


The value of R5 and R6 can be determined using this formula:

Vo=1.23(1+R5/R6)

Where 1.23= Vref (reference voltage of the IC)


Here, we need Vo = 12V, then assume the value of either R5 or R6 then find for the other.

Eg. choose R6=2.0kΩ, put the value in the formula, we get R5=17.4kΩ. Hence, the values.


There could be a difference between ‘Operating Ratings’  and ‘Absolute maximum Ratings’ of the boost up converter. They could also operate at absolute ratings, but it is recommended to run them under maximum operating ratings. And for that you might need to refer to the datasheets.
