Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and […]

Infineon Technologies AG broadens its EiceDRIVERâąÂ portfolio with the 650 V half-bridge gate drivers based on Infineonâs unique silicon on insulator (SOI) technology. The products provide leading negative transient voltage immunity, monolithic integration of a real bootstrap diode, and superior latch-up immunity for MOSFET and IGBT based inverter applications. These unique features enable more robust and reliable designs
A switched capacitor voltage converter performs energy transfer and voltage conversion using capacitors. There are mainly two types of switched capacitor voltage converters, first is the voltage inverter circuit and the second is the voltage doubler circuit. These types of circuits are commonly known as charge pump circuits. In this project, we will design a switched capacitor voltage inverter using Texas Instruments LMC7660S IC, and

Buck-Boost regulator is made using two different topologies, as the name suggests, it consists of both buck and boost topology. We already know that Buck Regulator Topology provides a lower magnitude of output voltage than the input voltage, while a Boost Regulator Topology provides a higher magnitude of output voltage than the provided input voltage. We have already built

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave, square wave, Sawtooth wave, etc. We have already designed sine wave generator circuit, square wave generator circuit, and sawtooth wave generator circuit. Now in this tutorial, we will show you, how to

Oftentimes in an electronic circuit, it’s absolutely necessary to use a special protection unit to protect the circuit from overvoltage, overcurrent, transient voltage, and reverse polarity and so on. So, to protect the circuit from these surges, Richtek Semiconductor introduced the RT1720A IC which is an oversimplified protection IC designed to meet the needs. The
A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but the direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage

Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we can make a series of bulbs look beautiful for outdoor decoration in Cafeteria, Restaurants, etc. or even used it for heavy Christmas light decoration,

A crude way to power your DC circuits with AC mains is to use a step-down transformer for stepping down the 230V mains voltage and adding a couple of diodes as a bridge rectifier. But due to the huge space size and other drawbacks, it cannot be used for all purposes. Another most popular and professional

For microcontrollers, an LED blinking program is equivalent to the âhello worldâ program. In our previous tutorial, we learned how to get started with STM8S103F3 Development Board and how to set up the IDE and compiler to program our STM8S controllers. We have also learned how to use the standard peripheral libraries, and how to compile and
