压电发声器驱动器如何在更宽广的电池电压范围内提高声压级
压电发声器在许多产品应用中，用来产生警告或警示音，通常用于可携式、电池供电和节省空间的产品。这些装置由连接到金属板上的陶瓷组件组成，对装置施加电压时，陶瓷组件产生的压电效应，会让金属板变形。随着电压的变化，陶瓷组件会跟着收缩和膨胀，连接的金属板也因此振动而发出声响。

New Advances in LED Control Systems for Automotive Exterior Lighting
The automotive lighting market continues to grow strongly and is forecast by analyst Yolé to reach US$38.8 billion by 2024. Over the past few years, LEDs have taken an increasing share of this market, and LED exterior lights have become a familiar sight on our roads.
PCIe Generations from Leading-Edge to Legacy, Desktop to Data Center
The global appetite for data shows no sign of abating and continues to place pressure on service providers to handle more bits, more quickly.
Brushed DC Motors and How to Drive Them
DC electric motors have been around for nearly two hundred years, with a steady series of refinements in that time. More recently, brushless DC motors have become increasingly popular but for many applications brushed DC motors are still the right choice.
晶体振荡器如何让数字电子装置同步化
在家里或工作中遇到的大多数电子系统将包括至少一个振荡器作为时钟工作，提供准确的定时，同步操作或作为频率参考。在这里，我们将看到使用石英晶体振荡器的许多好处，并讨论可用的选择。
BoM and PCB Space Savings Achieved with Control Channel Aggregation for Optical Interfaces
Fibre optic networks bring the promise of fast broadband to new customers all around the world. It increasingly reaches new limits, but to provide a guaranteed level of service, that bandwidth must be managed effectively. A significant factor to that effectiveness is how it interfaces with other network equipment running over copper cable.
Integrated Solutions to USB Type-C Port Implementation Challenges
Highly integrated solutions for USB 3.2 data switching, USB Power Delivery and USB Battery Charging control, and transient protection help designers unleash the full potential of the USB Type-C interface.
汽车应用中新增瞬态电压抑制功能
In automotive applications, it’s essential to protect sensitive semiconductor components against power surges, transients and electrostatic discharge (ESD). A single transient voltage spike could easily damage or disrupt a component, while electrical noise of even relatively low energy can cause significant interruption to digital communications.
Improving Power Conversion Efficiency with Super Barrier Rectifiers
For the design of almost any electronics or electrical system, it’s important to maximise power efficiency. In mobile devices, better power efficiency delivers longer battery life, which is a key selling point. For basically any application, improving power efficiency means that size and weight can be reduced, and thermal management simplified – thus reducing costs. Of course, using less power also helps products to meet energy rating requirements, which may be a legal requirement, and an attractive feature for customers.
自然语言就是新一代的用户接口
The ‘perfect storm’ of high bandwidth internet connectivity, deep learning algorithms and high-quality audio is enabling a new paradigm in user interfaces: the spoken word. The ability to interact with household appliances and cloud-based services through natural language is truly a sea-change in the way people and machines interact.
