Core Insights - Apple Inc. has launched a new power adaptor that enables fast charging for iPhones without causing overheating, named the '40W Dynamic Power Adapter With 60W Max' [1] - The adaptor supports USB PD 3.2 AVS protocol, allowing for adjustable voltage supply to optimize charging for devices [2][3] - The new adaptor is part of Apple's strategy to enhance charging speeds for its latest iPhone 17 series, which can charge up to 50% in approximately 20 minutes with a 40W or higher adaptor [4] Product Features - The adaptor provides similar charging power to a 60W charger while being rated at 40W, showcasing its efficiency [1] - It is compatible with the latest iPhone models, including iPhone 17, iPhone 16, and iPhone 15 series [3] - In comparison, the previous iPhone 16 lineup charged devices to 50% in 30 minutes, indicating an improvement in charging speed with the new adaptor [5] Market Positioning - The introduction of this adaptor aligns with Apple's focus on faster charging solutions for consumer electronics, particularly for the iPhone 17 product line [4] - The adaptor is sold separately from the type C charging cable, which must be purchased independently [5]

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 ...
