As technology advances, engineers are constantly seeking ways to simplify design, reduce board space, and expedite the development process. MPS meets these demands by offering the widest portfolio of power modules on the market. These devices integrate the power stage, control loop, and in...

Powering field-programmable gate arrays (FPGAs) represents a challenge for power engineers due to their increasing number of logic cells, which increases complexity. In addition, these semiconductor devices are highly configurable, allowing designers to define the clock and phase-locked loop (PLL) frequencies, as well as configure the logic elements within them. Furthermore, defining the power con...

Signal transmissions are everywhere. In industrial applications, such as electric vehicle (EV) charging stations and automation systems with programmable logic controllers (PLCs), there is a high voltage (up to several kV) that can be dangerous to the human body. This type of hazardous voltage can also pass through the signal line, which can cause signal interference and could eventually destroy t...

In a DC/DC converter, the auxiliary power supply of multiple switching devices requires independent isolated power supplies. Taking a full-bridge converter as an example, the high-side and low-side MOSFETs (HS-FETs and LS-FETs, respectively) of the bridge arm require isolated power supplies for the gate driver circuit. The traditional scheme uses a bootstrap circuit to power supply both the upper ...

Data traffic is the center of modern life, with any mobile phone app nowadays requiring tens of hundreds of megabytes for installation packages. When several software updates are made, it is necessary to be connected to Wi-Fi. Loading a page while online shopping consumes several megabytes of traffic to load a single page, and video calls are prone to freeze if the Internet speed is not fast enoug...

Converter selection is the first step in power supply design that directly impacts stable system operation and performance. Typically, the designer must determine whether a power converter meets the actual load capacity based on the rated current value. For example, selecting a 36V/3A buck converter for a 24V to 5V/2A power rail achieves excellent efficiency, temperature rise, and cost performanc...

In the buck circuit, the inductor design is a key element that is closely related to system efficiency, the output voltage ripple (∆VOUT), and loop stability. This article discusses how to calculate the inductance of a buck converter using the MPQ2314 as well as key parameters including the rising current of the inductor temperature, saturation current DC resistance, operating frequency, and magne...

The electrical appliances we use in our daily lives — from lights to computers — typically go through a shutdown process when they turn off. Power supplies require stable shutdown processes that can control for unexpected overshoot. In a stable shutdown process, the power supply smoothly drops the input voltage (VIN) to 0V. For a stable shutdown, there should a steady VIN drop, no negative output...

For battery-powered applications, an excellent user experience depends on a long battery life and high-performance terminal devices. Quiescent current (IQ) is an important parameter to consider when optimizing these applications; in particular, an improved IQ increases battery life. This article will describe the difference between a boost converter’s IQ and shutdown current (ISD) to provide a de...

An unexpected pandemic has disrupted design timelines across the globe. Because design teams must work from home, manufacturers have experienced numerous product delays or even cancellations. MPS simulation tools can help users speed up their design process. By displaying a part’s performance and offering debugging assistance, these tools help users select the right products. These have prov...
