USB与无线充电
概览
USB-C电池充电器已成为现代电力传输的基本元素，可为智能手机、笔记本电脑、平板电脑、电动工具和新兴大功率设备等广泛的消费类和便携式应用实现快速、高效和通用充电。随着 SB Type-C和最新US供电（PD）标准的广泛采用，充电系统现在可支持双向功率流、动态电压和电流协商以及更高的功率级别。带有扩展功率范围（EPR）的USB-C PD 3.0/3.1将输出能力扩展到240W，可编程电压扩展到48V，加快了充电时间，同时将USB-C扩展到新的应用领域。与此同时，监管机构对效率和待机功耗的日益关注推动了对先进电源转换架构和更高系统集成的需求。
为了满足这些需求，安森美的USB-C电池充电器解决方案以可扩展、高效的架构，覆盖65W-240W的AC输入和DC输入设计。这些方案集成了关键功率级，包括功率因数校正（PFC）、使用反激式或LLC拓扑的DC-DC转换、同步整流以及支持PPS的精确PD控制，从而提供紧凑、热效率优秀的设计。利用氮化镓（GaN）和集成驱动器氮化镓（iGaN）等宽禁带（WBG）技术以及优化的硅和碳化硅器件，能够实现更高的开关频率、更高的功率密度和更高的整体效率。在经过验证的参考设计、评估板以及全面的控制器和功率器件组合的支持下，安森美为下一代USB-C PD充电器提供了可直接投入生产的完整基础支持。

Low/Medium Voltage MOSFETs
Portfolio of comprehensive range of Low-medium voltage power Mosfets that delivers superior performance and reliability for switching applications. Our cutting-edge PowerTrench® T10 technology delivers industry leading RDS, higher power density, reduced switching losses and better thermal performance.
Silicon Carbide (SiC) Cascode JFETs
Our high-performance SiC cascode JFETs deliver best-in-class switching speed, lower switching losses, and higher efficiency. They provide high switching frequency and deliver ultra-low on-resistance (RDS (on)) starting at just 5mohm, utilizing less than half the die size of any other technology. Available in both standard thru-hole (including Kelvin) and surface mount packages, they offer excellent cost-effectiveness.
These devices utilize a unique cascode configuration, integrating a high-performance SiC fast JFET with a cascode-optimized Si-MOSFET. This innovative approach enables standard gate drive (0-12V) for SiC devices. Given their smaller die size and compatibility with existing driver solutions, the SiC cascode JFETs offer optimized system performance and cost structure.
