APPLICATIONS
AC-DC Adaptor
The AC-DC adaptor is more than a device you throw in your bag to ensure your battery doesn’t die when it’s needed most. It also enables seamless connectivity and mobility for modern lifestyles where work and play are always in motion./ Empowering Connectivity from Anywhere
For consumers, the AC-DC adaptor is likely an afterthought until their notebook battery reaches less than 50%. These necessary components do more than convert alternating current from the grid to direct current required by computer batteries — they enrich our lives daily through:
- Productivity - gone are the days of being in the office to access important files, check emails, or complete work-related tasks
- Communication - constant connectivity ensures seamless communication through emails, video calls, and messaging platforms
- Information access - whether it’s a Google search for personal use or accessing important work files in the cloud, AC-DC adaptors ensure you’re charged for the task
- Flexibility - remote work has gained popularity in recent years, providing employees with off-side, in-office, and hybrid arrangements
- Emergency preparedness - the ability to be connected during an emergency or outage ensures access to critical safety information when it’s needed most
- Entertainment - being bored is never an option, thanks to multimedia content, streaming services, and gaming capabilities from the airport, destination, or wherever
- Collaboration - access to shared documents and online platforms facilitates anytime, anywhere collaboration for work or play
- Navigation - location-based services like GPS are essential for life on the go
- Social networking - connecting with friends and family on social media is integral to everyday life
- Continuous learning - online courses, educational platforms, and tutorials facilitate learning no matter the location
/ Application Considerations
Engineers should specify components after careful consideration of the following aspects that impact overall design, performance, and safety of AC-DC adaptors:
- Efficiency - adaptors should be as energy efficient as possible to reduce power losses and heat generation
- Voltage regulation - the adaptor must deliver the appropriate voltage and current levels required by the specific computer, and some designs include selectable voltage outputs for use in various computer models
- Overcurrent protection - overcurrent and overvoltage protection circuits are essential to maintain safe operation and safeguard sensitive components
- Heat Dissipation - proper heat sink and thermal management mechanisms should be in place that are appropriate for the size and type of adaptor
- Size and weight - a compact and lightweight design is essential for portability, but it must not come at the expense of reduced performance
- Electromagnetic interference (EMI) mitigation - to ensure compliance with industry standards and prevent interference with other electronic devices and components, EMI filtering is recommended
- Safety standards - compliance with all applicable safety regulations and standards must be achieved, such as UL, CE, and the FCC
- Compatibility - connector tips can vary per laptop, so using interchangeable tips or a design with universal appeal is recommended
