Linear applies switched-capacitor step-down topology for inductor-less DC/DC
https://www.electronics-lab.com/linear-applies-switched-capacitor-step-topology-inductor-less-dcdc/
Graham Prophet @ eedesignnewseurope.com discuss about the new Linear’s step-down inductor-less controller. LTC7820 is, a high power fixed ratio charge pump DC/DC controller that eliminates the power inductor in a non-isolated intermediate bus converter, allowing up to a 50% reduction in circuit size and up to 4000 W/in³ power density. The 72V fixed-ratio DC/DC controller […]
SUNY Polytechnic Creates 3-in-1 Device That Can Be A Diode, A MOSFET And A BJT
https://www.electronics-lab.com/suny-polytechnic-creates-3-1-device-can-diode-mosfet-bjt/
In a recently published study, a team of researchers at SUNY Polytechnic Institute in Albany, New York, has suggested that combining multiple functions in a single semiconductor device can significantly improve device’s functionality and efficiency. Nowadays, the semiconductor industry is striving to scale down the device dimensions in order to fit more transistors onto a computer […]

5V to Dual 12V Step Up DC-DC Converter Using LM2588-ADJ
https://www.electronics-lab.com/5v-dual-12v-step-dc-dc-converter-using-lm2588-adj/
Lots of op-amp based circuits require dual (symmetrical) power supply. This tiny circuit is a simple solution which provides +/-12V DC 300mA from single 5AV DC input. The board is based on LM2588-ADJ IC from Texas instruments. Step up from 5V to dual 12V is the best part of the circuit since 5V is easily […]

First Thoughts on the New ROCK64 Board
https://www.electronics-lab.com/first-thoughts-new-rock64-board/
Alasdair Allan @ hackster.io writes: The original Pine A64, hailed by many as a “Raspberry Pi killer” during its crowdfunding campaign, shipped to backers to somewhat poor reviews back in 2015. However after a lot of work by the manufacturer, software support for the board is now much improved. The recent release of the Pinebook […]
