Our broad portfolio of AC/DC converters, DC/DC converters, and switching regulators allows us to support power requirements from board-level point-of-load conversion to isolated power and direct AC mains conversion.
- Why do we need an AC/DC converter?
Most electronic devices operate on low-voltage DC power, while power from the mains is supplied as high-voltage AC. An AC/DC converter safely converts the AC mains voltage into the regulated DC voltage required by the electronic circuit.
A properly designed AC/DC converter also provides:
• Voltage conversion and regulation: Delivers a stable DC output at the voltage required by the load.
• Electrical isolation: Provides galvanic isolation between the hazardous mains supply and the low-voltage circuitry for safety.
• Protection: Helps protect the system against abnormal conditions such as overvoltage, overcurrent, and short circuits.
• EMC performance: Helps reduce conducted and radiated interference to meet applicable EMC requirements.
Using a compact AC/DC power module can significantly simplify power supply design, reduce development time and board space, and make it easier to meet safety and EMC requirements.
- Why do we need a DC/DC converter?
There are many reasons to use a DC/DC converter, but the most common applications include:
• Voltage conversion: To match the power supply to the load by stepping the voltage up or down, generating dual outputs, or inverting a supply rail.
• Electrical isolation: To isolate primary and secondary circuits for safety, noise reduction, or protection of sensitive circuitry from interference.
• Power system simplification: Using multiple-output converters can simplify power architecture, reduce overall cost and board space, and improve flexibility, reliability, and system efficiency.
- Why do we need switching regulators?
Switching regulators efficiently convert one DC voltage to another while maintaining a stable, regulated output voltage.
Compared with linear regulators, they offer much higher efficiency and lower heat dissipation, especially when there is a large difference between the input and output voltage.
Depending on the topology, they can step down (buck), step up (boost), or invert the input voltage.
Their high efficiency and compact size make switching regulators ideal for applications where power efficiency, thermal performance, and board space are important.
- What certifications do our industrial power solutions have?
Most of our AC/DC converters are certified to IEC/EN/BS/UL 62368-1 and IEC/EN/BS 60335-1 & IEC/EN 61558, with approvals from internationally recognized certification bodies such as UL and TÜV.
This comprehensive certification coverage supports a wide range of industrial, ICT/AV, and household appliance applications, giving customers greater flexibility when integrating our products into different end systems. Having this combination of major safety approvals across our AC/DC portfolio is not commonly available in the market and can help simplify customers' end-product certification processes.
For DC/DC converters, certification coverage is generally less extensive than for AC/DC products, as DC/DC converters typically operate at SELV/low-voltage levels, where independent safety certification is often not mandatory. Nevertheless, all Favotek DC/DC converters are designed to meet the applicable safety requirements of EN 62368-1, and most of our high-demand models are certified to IEC/EN/UL 62368-1.
- Do AC/DC converters require any external components?
All our AC/DC converters feature built-in input filtering and can operate without external components. However, depending on the application and safety requirements, an external input fuse may be required. The -CT/-CR options, with the converter pre-mounted on an insulated PCB and equipped with screw-terminal input and output connections, includes an input fuse as standard.
- I have temperature problems. Can I use a heat sink to extend the operating temperature range?
Most converters require output power derating above a certain ambient temperature, typically between 70°C and 85°C, depending on the model.
A heat sink can improve thermal performance and may allow the converter to deliver full power at a slightly higher ambient temperature. However, its effectiveness depends heavily on airflow and the overall thermal design of the system. In a poorly ventilated or enclosed application, even a large heat sink may provide limited improvement.
In such cases, selecting a higher-power converter and operating it at a lower percentage of its rated load is often a more effective solution.
- What is isolation?
Isolation refers to the galvanic separation between the input and output of a power converter. In an isolated converter, there is no direct electrical connection between the input and output circuits.
This isolation helps block unwanted current paths, voltage differences, electrical noise, and fault currents from passing between the two sides. It is particularly important in applications where safety, noise immunity, or protection of sensitive circuits is required.
Depending on the application, isolation may also be necessary to meet specific safety and regulatory requirements.
- Are Favotek products burn-in tested during production?
Yes. All Favotek products undergo a minimum 2-hour burn-in test at our factory before shipment to ensure product quality and reliability.
- I cannot find a product that meets my requirements. Can Favotek provide a customized converter?
Yes. In addition to our standard product ranges, Favotek offers customized power solutions tailored to specific application requirements.
We can customize key parameters such as input and output voltage, output power, package, pin configuration, protection features, and other electrical specifications, depending on the application and project requirements.
Prototype samples can typically be developed within a relatively short timeframe. Please contact Favotek with your specifications and expected volume, and our engineering team will evaluate the most suitable solution.
For modified custom designs, we can develop and deliver samples within 4–8 weeks, while new designs typically require 8–12 weeks.
- Why is Favotek more cost-effective than our competitors?
Favotek's competitive pricing comes from two key advantages:
Efficient supply chain and manufacturing: We leverage China's well-established electronics supply chain and maintain tight control over manufacturing costs and operational efficiency.
A distribution-focused business model: We focus our resources on product development, engineering, and manufacturing, while working closely with our distribution partners for local market development and customer support. This keeps our organization efficient and allows us to offer competitive pricing with attractive margins for our partners.
Our goal is not simply to offer lower prices, but to deliver a strong balance of quality, performance, technical support, and cost while building sustainable, long-term partnerships with our distributors.
- What is the typical delivery time?
Our standard lead time is typically 4–8 weeks for high-demand products and up to 12 weeks for less frequently ordered models, depending on material availability and order quantity.
For many popular models, we maintain finished goods or material safety stock to support faster delivery. For larger projects and scheduled orders, we also work closely with our customers and distribution partners on forecasts and production planning to ensure reliable and consistent supply.
For urgent requirements, please contact our sales team to check current stock and the earliest available delivery date.
