ADI Offers the New µModule Regulator that Powers Noise Sensitive Applications

In late March Analog Devices Inc. (ADI) launched a super low noise dual output DC/DC µModule regulator. The layout is a patented silicon base, and several packaging changes the company is saying are innovations.

ADI is saying the LTM8080 operates from up to 40V input and the front end is a high-efficiency synchronous Silent Switcher step-down regulator. This is followed by two separate low-noise, low-dropout (LDO) regulators.

Transphorm and Weltrend Launch Their First GaN System in Package

Transphorm and Weltrend launch their first GaN System in Package. In collaboration with WelTrend Semiconductor, Transphorm Inc. has released its first GaN System in Package (SiP).

The WT7162RHUG24A is an integrated circuit (IC) that is used in 46 to 100-watt USB-C PD power adapters. The uses for this adapter are varied and include smartphones, laptops, tablets, and many other smart devices.

The peak power efficiency is greater than 93%.

Marvell Launches a 200Gbps Lambda Optical DSP

In a first in the industry, the Marvell Nova 1.6tbps PAM4 electro-optics platform is powered by a 200 Gbps optical DSP.

The system is geared toward high-speed data movement in cloud artificial intelligence (AI), Machine Learning (ML), and data center networks. The core of emerging generative AI applications are AI clusters, made up of thousands of supercomputers all interconnected. The interconnection is run by ultra-high bandwidth and low-latency optical connections.

Power is Running Away With the Cloud

This week Circuit Cellar aficionados there can't be any better way to

talk about what is happening in the analog world then with the Digital Signal Processor (DSP) that will help interconnect thousands of super computers throughout the world and even in space.

The main function of these super comps is to gather and send great behemoths of data to waiting data hounds throughout the world. AI will be the main computational routine, but its the data that matters and now terra-bits can be sent every second.

Opening the doors to an intelligence that can not be denied, or maybe regulated, we are becoming an advanced world society so quickly our technology is unable to move fast enough to ride the vast wave of data that is breaking on the shores of our tech industry.

But it will surely come into open waiting arms and with satisfaction. Keep an eye on this space

In the new year we will be asking for opinions, what would you like to see, more editorial or less, more of a particular topic, or less? Let us know. Reach out to the Product Editor
