Successful use of DC-DC buck/boost regulators in systems

The role of a DC-DC switching converter is to efficiently convert one DC voltage into another. High-efficiency DC-DC converters use three basic technologies: buck, boost, and buck/boost. Buck converters are used to generate low DC output voltages, boost converters are used to generate high DC output voltages, and buck/boost converters are used to generate output voltages that are less than, […]

Dry goods | Comparison between gateway redundancy protocol HSRP and VRRP technology

Comparison between Gateway Redundancy Protocol HSRP and VRRP Technology A redundancy protocol generally refers to a protocol that prevents network equipment from failing. Now there are three redundancy protocols: VRRP of IETF, HSRP of Cisco, and NSRP of JUNIPER. Today, let’s compare the differences between Cisco’s HSRP and Huawei and H3C’s VRRP protocols. HSRP: (Hot Standby Router Protocol) – Hot […]

This small device becomes the next battlefield for semiconductors

2021 was supposed to be the year of AMD’s explosion. Relying on the TSMC process, which is one generation ahead of Intel, AMD will continue to push Intel step by step. Bernstein Securities optimistically predicts that AMD’s market share in CPU this year will further surge from 10% in 2020 to 13%. It is expected that it will become the […]

This is the real strength of China. The number of IoT terminals exceeds 1.3 billion. The United States and Japan are really behind this time.

The picture shows the Internet of Things technology Now that China’s strength is revealed, the number of IoT terminals exceeds 1.3 billion. In this process, Huawei can be said to have made a great contribution, because the number of IoT interruptions in China has far exceeded that of the United States and Japan! It seems that this is the real […]

Unique: Infineon develops advanced hydrogen sulfide protection to extend the life of IGBT modules

[Munich, Germany, July 9, 2020]Durability determines the longevity and reliability of modules in harsh environments. Especially when exposed to hydrogen sulfide (H2S), the lifetime of Electronic components can be greatly affected. To counter this threat, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has developed a unique protection feature. EconoPACK™+ modules featuring the TRENCHSTOP™ IGBT4 chipset are the first in […]

Integrated circuit with cable balancer to reduce radiation from cable system

“With the advent of integrated circuits with balanced cable loss effects, system designers have the ability to transmit high-speed data over very long copper cables. In communication system design, it is important to control radiation from cables and connectors for optimum performance. The ability of an integrated circuit to balance out the effects of cable loss is a major cost […]

“Lack of core” has a huge impact, and the core base of this car company may stop production!

Since Volkswagen stopped production in early December 2020 due to the shortage of ESP chips from Continental and Bosch, the “chip shortage” problem has successively affected global car companies. Supply is tight and production plans at some factories have been suspended, involving a number of hot-selling models. Not long ago, the production capacity of domestic new energy vehicle upstarts such […]

How to correctly understand the op amp input offset voltage?

[Introduction]Digital power system management (PSM) controllers are typically targeted for high-current point-of-load (POL) applications. Lower current applications (with up to 6A load current) can also benefit from the PSM feature. The LTC3815 is a 6A monolithic synchronous step-down converter with digital power monitoring and control. The input offset voltage Vos (Voltage – Input Offset) refers to the compensation voltage that […]
