Apple Inc. launched a new power adaptor that can fast charge an iPhone without heating it up. The '40W Dynamic Power Adapter With 60W Max' can disseminate a volume of power higher than the amount of syllables in its lengthy name.A part of the company's latest iPhone 17 launch on Sept. 9, it can provide similar charging power to that 60W charger despite being 40 W. It achieves this through its USB PD 3.2 AVS protocol support.This means that it has an adjustable voltage supply, giving the user different volta ...

Core Insights - ROHM Semiconductor has developed the AW2K21, a 30V N-channel MOSFET with an industry-leading ON-resistance of 2.0mΩ in a compact 2.0mm × 2.0mm package [1][11]. Product Development - The AW2K21 addresses the growing demand for fast charging in compact devices, which require bidirectional protection to prevent reverse current flow [2]. - The new MOSFET integrates two devices into a single package, optimizing space and complexity in power supply and charging circuits [3]. Technical Specifications - The AW2K21 features a proprietary structure that enhances cell density and minimizes ON-resistance per unit chip area, achieving a maximum current rating of 20A and breakdown voltage between 28V and 30V [2][4]. - Compared to standard solutions that require two 3.3mm × 3.3mm MOSFETs, the AW2K21 reduces footprint and ON-resistance by approximately 81% and 33%, respectively [5]. Competitive Advantage - The AW2K21's design allows for a larger chip-to-package area ratio, further reducing ON-resistance per unit area, making it suitable for high-power fast charging applications [4]. - It maintains the lowest ON-resistance in the industry for unidirectional protection MOSFETs in load switch applications [8]. Future Developments - ROHM is committed to further miniaturization and energy efficiency, with plans to develop an even smaller 1.2mm × 1.2mm model [8][9]. - The AW2K21 is set to launch in April 2025 and will be available through online distributors such as DigiKey™, Mouser™, and Farnell™ [9].

乘用车中，纯电车对于普及快充最为焦虑。若以800V高压平台为观测窗口，从2022年的13款增至 2023年的37款，再到2024年前五个月的48款，实现成倍增长。 以"15分钟到80%"为技术焦点，面向多元车型、不同成本价位的快充诉求，动力电池快充技术向三大方 向分化。 快充价格门槛的降低在纯电快充车上表现得最为突出。 2024年中国20万元以上纯电车型已普遍配 置800V高压快充，据相关预测，2026年搭载800V高压平台的车型销量将达580万辆，渗透率突破 50%。小米SU7、极氪007、智界S7等代表快充车型在20万元的价格区间激战正酣，极狐阿尔法S5 则是直接将800V高压平台的配置门槛拉至20万元以下。 2月20日，华为在鸿蒙智行尊界技术发布会上推出全球首款800V高压6C动力电池包——巨鲸电池 2.0，并宣布今年将首发搭载尊界S800，6C动力电池即将开启装车。 在电动车成本更低、使用感更佳的影响下，混动车用户的用能倾向从油逐渐向电过渡。 快充技术 也从最初聚焦纯电动车，向增程式混动和高端插混车型扩展。 2025年混动车型也开始强调"快 充"卖点，华为尊界S800混动版、比亚迪2025款汉DM-i ...
