Tagore Technology has been delivering disruptive GaN semiconductor solutions for more than 12 years. The reference design uses Tagore’s TP44100SG (90mOhm) and Inventchip’s CCM Totem Pole…

An ac-dc converter is commonly used in many devices. Also called a rectifier, it converts alternating current (AC) to direct current (DC). Most electronic devices, such as computers, smartphones, and electronic circuits, operate on DC power. However, there are different ways to convert AC into DC power (as discussed in the previous AC-to-DC conversion article). For…

by Sebastiano Grasso, Leonardo Agatino Miccoli, Giusy Gambino, Filippo Scrimizzi, STMicroelectronics, Catania, Italy The automotive landscape constantly evolves, driven by the increasing demand for automation, safety enhancements, and power efficiency. Within this dynamic environment, the deployment of DC motors in automotive body applications has gained significant prominence. These versatile motors find application in both traditional combustion…

This tutorial explains the process of ac to dc conversion and why it is needed. The electricity that is delivered to our home is mainly AC (Alternative Current). Different countries have different standards for domestic AC lines ranging from 100 V to 220 V. Even so, most home appliances are DC (Direct Current)-operated, although devices…

The term transistor is derived from the words “transfer and “resistor.” The first semiconductor transistor was invented to replace the triode as an amplifier device, a vacuum tube with three electrodes. The transistor was smaller, lighter, and cheaper than a vacuum tube triode. It also proved easy to construct and had no heat losses like…

In many applications, there’s a need for a constant voltage source. However, there are more constant current source applications than constant voltage sources. Most power supplies are voltage sources, including batteries and bench power.  A constant current source can be used anywhere a fixed current is required. A resistor can also be used, but the…

In this era of battery-operated devices, a DC-DC converter is needed to meet the divergent power requirements of the electronic circuitry. A battery is a type of DC Supply whose output voltage varies with its use. This means it cannot maintain a constant voltage at the output due to its discharging characteristics. For this reason,…

Nowadays most of our devices are portable and run on batteries. We often do not know when the battery is about to get discharged. Many systems have the battery voltage display to indicate the battery voltage but what if we don’t have the display in our system. In such a case, using a small LED to indicate low battery is very helpful for users to know about the battery status.

The battery stores electrical energy in form of chemical energy and the chemical energy again able to convert into electrical energy. The conversion of chemical energy to electrical energy is called discharging. The chemical reaction during discharge makes electrons flow through the external load connected at the terminals which causes the current flow in the…

A DC power supply is used in almost all of devices where a regulated voltage is required. A DC converter implements the process of DC conversion. There are two types of DC converters: Buck converter- Steps down the input source voltage Boost converter – Steps up the input source voltage Conversion topology Linear regulator –…

Everyone must be familiar with the term – Switched Mode Power Supply or SMPS. Yes, they are used in every personal computer. In fact, the Switched Mode Power Supply is widely used with many other devices. Once it is understood that what SMPS actually is, its countless applications can be easily imagined.  

Power consumption of the embedded controller is a primary concern in low power design. Arduino boards are often used in devices that rely on battery or solar charging. Such devices often deploy far from the power line to have periodic battery replacement or are mobile devices designed for periodic charging cycles. In such a case,…

There are generally six power modes in an MCU: Run: In full run mode, an MCU consumes full current. This mode is best suited for applications where power efficiency is not essential. Doze: As we know, power increases proportionally to the frequency. Therefore, we can conclude that higher clock speeds tend to higher power consumption.…

In the previous article, we learned what a low-power system is so now we’ll talk about the key factors using which we can make power-efficient embedded system design. The power-efficient embedded system is comprised of hardware and software design along with proper components selection. Optimization is achieved by efficient implementation in different stages using different…

Low power design is a system using a collection of techniques and methodologies for the purpose of optimizing battery life and reducing the overall power dissipation of the system. To optimize the power there are many low power techniques that depend on the level of the design selected, ranging from semiconductor technology to the higher…
