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…
How to design a lab power supply at home
The voltage requirements for different circuits vary much like microcontroller-based circuits require 5 V, motor controller or relay driver circuit requires 12 V, and other digital circuits require 3.3 V. If a circuit fails to receive its rated voltage and current, it will not work properly. So, it often makes sense to use a variable…
Diodes brings power-efficient, low-latency operation to USB-C/DP designs
Diodes Incorporated (Diodes) (Nasdaq: DIOD) is targeting growth opportunities in USB Type-C technology, and lower power operation needs, with two new bit-level retimers The DIODES PI2DPT1021 is a bit-level retimer with receiver adaptive CTLE and transmitter 3-tap equalization that can compensate channel loss up to -23dB for 5GHz signal transmission. It supports DP1.4 and USB3.2…
Infineon expands its fixed-frequency CoolSET portfolio
Optimized performance, efficiency, and reliability in high-voltage power supplies need to be combined with reduced bill-of-material (BOM) count and cost, as well as lower design efforts. With its 5th generation fixed-frequency (FF) CoolSET portfolio, Infineon Technologies offers the ideal components to meet these needs and effectively manage the critical design trade-offs. The new 800 and 950 V AC-DC…

Due to their unique technological characteristics, they enable the highest performance and energy efficiency. With a commitment to these domains, Infineon Technologies and Delta Electronics, Inc., are deepening their collaboration to deliver superior solutions for the convenience of end customers. The…
New TI processors make edge AI more accessible
Expanding on its history of delivering highly integrated processors, Texas Instruments (TI) has introduced the new Sitara AM62 processors that help expand edge artificial-intelligence (AI) processing into next-generation applications. The low-power design of the new processors enables support for dual-screen displays and small-size human-machine interface (HMI) applications. TI will showcase the new AM62 processors and…
CUI offers new 300 and 120 W compact GaN adapters
CUI Inc, a Bel group company, has announced the expansion of two GaN desktop ac-dc power supply series to its SDI product family, broadening their product range for the GaN adapter line. The SDI300G-U and SDI300G-UR offer 300 W of continuous power from a compact desktop package and boast up to 100% increase in power…
TI’s new transformer module technology maximizes EV drive time
Texas Instruments (TI) recently introduced the industry’s smallest and most accurate 1.5-W isolated DC/DC bias-supply module. The UCC14240-Q1 uses a proprietary integrated transformer technology to enable designers to cut their power solution size in half for use in high-voltage environments such as electric vehicles (EVs), hybrid EVs, motor-drive systems, and grid-tied inverters. With the accelerating…
