About this deal

Mind that some modules mention that operating at max current might require an additional heat-sink or cooling solution. A resistor can only provided a fixed voltage drop if you send exactly the same current through it at all times.

This circuit is actually less efficient than circuits 1 and 2, because extra current is needed for the Zener and its associated resistor. I was not concerned with the ripple as in my scenario the output of the buck goes to a linear regulator.The basic Buck converter circuit consists of the switching transistor, together with the flywheel circuit. These have one more use for us, We originally tried to drive some high power MOSFETs with poor response, but after adding pull up resistors to the gates, and IO static with a pull down resistor set internally on the pin, we get very reliable control. to work with a Matrix Orbital LK204-25 LCD (5v) using a I2C interface, I needed a bi-directional logic-level converter.

As we know that high-powered devices plays an important role in various applications, from power amplifiers to motor control, so understanding its features, characteristics and capabilities is essential. The LT1173 consumes just 110µA supply current at standby, making it ideal for applications where low quiescent current is important. The two on the left are input, the two on the right output with the negative terminals next to each other for safety.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. Since we don’t want our device to reset during crank-ups we would like to perform conversion of input voltage of 7 to 20 volts to a fixed 5 volts output that the Arduino Uno expects.
