The step-up converters (also known as a boost converters) is an power electronic converter, which is designed to increase the direct voltage (DC) from the source, receiving an appropriately increased DC voltage for the receivers at the output. The main purpose of devices such as DC-DC voltage converters, step-up and step-down converters is to power various types of electronics.

How does a step-up converter work?
In the circuit of a typical step-up converter, a transistor key and a diode are used. When the switching transistor conducts, it closes the circuit through the coil and the power source, and the diode in the switching circuit turns on because the voltage at its cathode is higher than at its anode. The basic rule in step-up converters is that the coil operates by maintaining continuity of current due to changes in the magnetic field, and the voltage at the output is always higher than at the input. When the transistor conducts, the current flowing through the coil creates magnetic field energy. When the switching transistor stops conducting, the current flowing from the source through the coil disappears. The previously accumulated magnetic field energy is, in accordance with Faraday's law of induction, changed into a voltage summed with the source voltage, which powers the receiver through a diode and charges the voltage-maintaining capacitor connected in parallel. The keying transistor is controlled by a square wave signal with variable duty cycle (PWM) - the higher the duty cycle of the signal, the higher the voltage at the output of the step-up converter.
High-quality adjustable step-up converters
The U3V70X family of step-up converters from Polou are high-performance converters with synchronously switching regulators that require a minimum voltage of 2.9V. Immediately after switching on, the regulator limits the input current to 10.0A. The converters are equipped with overload, short-circuit and undervoltage protection, and the recommended maximum continuous output current is 6.0A. The output current is proportional to the ratio of the input voltage to the output voltage, which means that the output current decreases as the output voltage from the converter increases. Polou converters also have built-in protection against reverse polarity voltage, thus protecting the receivers. The built-in low power consumption function prevents unnecessary energy loss. The U3V70X family converters are available in a version with a rigid output voltage in variants from 5.0V to 15.0V and in a version with a precisely regulated output voltage in variants from 4.5V to 20.0V, using a 12-turn potentiometer.
Step up converters, also called power electronic converters, are devices that enable increasing the direct voltage (DC) from the source and obtaining at the output (step up converters) a voltage increased by a specific value. Step up converters are extremely important elements of switching power supplies. Selected converter models are equipped with systems that enable control of the output voltage within a specific range. This solution enables stable and safe power supply of power receivers with different supply voltage requirements.
The type, number and maximum power of current receivers depend strictly on the specific type of converter (specifically its current parameters and application). Low- and medium-power receivers can be connected to car converters powered by batteries (the exception is high-power converters powered by high-capacity batteries). Converters in the form of single-board systems allow the connection of current receivers whose voltage and current do not exceed the nominal parameters of the converter.
An unloaded converter connected to a power source consumes the so-called no-load current. The specific consumption value is strictly dependent on the model and electrical parameters of the converter. Low-power devices draw from several dozen to several hundred milliamps. In turn, high-power converters can draw up to several amperes.
