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…
How to design a power supply for Raspberry Pi
In this do-it-yourself circuit, we’ll design a Raspberry Pi (RPi) power supply. First, we’ll create a list to follow as a blueprint for the circuit, ensuring we design it correctly. Let’s start with a list of our goals for the circuit. Goals 1. A steady power supply: Ensure RPi receives a consistent and stable…
How to design an ac-dc buck converter
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…
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…
