Audio Products – Power Modules

ICEpower has developed and manufactured class D amplifier and switch-mode power supply modules for more than two decades. Today, we offer you a wide selection of Power Modules including class D amplifier modules with on-board, matching switch mode power supply, separate class D amplifier modules, and separate power supply modules.

Our Power Modules provide a platform to base a design upon, offering several advantages:

Faster time to market with lower risk
Samples in stock and available from our website with next-day shipment enable you to quickly evaluate and assess our platforms and rapidly start up development. With the amplifier and/or power supply is taken care of, you can focus on the other elements of your design. Basing your design on a known, proven quantity also takes the risk out of your project.

Our power modules are designed and manufactured to the highest standards. 20 years of experience has taught us how to create solutions that last and hold up, not just in the lab, but also under real-world use cases. Furthermore, all our products go through a thorough full functional test before they leave our production site. Our modules are market-proven with market returns below 0.3%.

Reliable, flexible, and cost-effective supply
We have long term relationships in place with two separate electronics manufacturers in Thailand and have our own staff on-site frequently. In addition, we maintain close relationships with all key sub-suppliers, including e.g. magnetics, MOSFETs, and other key components. When you use our modules, you tap into our combined sourcing and purchasing power, providing reliable, on-time delivery at competitive costs. All this without you having to get involved.   

Product maintenance
Whenever components go EOL or become hard to source, when there are new safety or EMC standards, then we take care of re-designing and updating the products. We do this while maintaining form, fit and functional compatibility. This means you don’t have to spend time and resources on updating the power section of your products – we do that for you.

Audio Products – Audio IC’s

Over the years, ICEpower has developed more than twenty class D amplifier ICs for a wide range of applications. These include high-end hi-fi, powerful professional audio amplifiers, mobile phones, automotive, and flat-panel TVs. We have gained considerable experience with class D semiconductor development through these projects.

While there are many companies doing class D ICs, for most of them, it is just a small segment of their business. They do ICs for everything – washing machines, alarm clocks, calculators, etc. Class D amps just happen to be one item in their portfolio. But ICEpower is different. All the ICs we do are class D amplifier ICs. 

In some cases, we offer design access with our ICs and reference designs. This can be a good solution if your specific project requirements fall outside our existing power module platforms and/or high volumes. In order to make commercial sense, typically the expected annual volume should be above 5-10k per year. 

ICEpower Audio ICs are flexible technology platforms for implementing high performance, high power, reliable class D amplifier designs, cost-effectively. Our class D Audio ICs are the cornerstone of our amplifier power platforms. Therefore, we have extensive and deep application expertise when designing with our ICs.

We can create reference designs for your specific application based on our large catalog of platforms to simplify and speed up your design process. In addition, when you work with our ICs, you get access to design support. Not just from FAEs covering a large portfolio of diverse products, but from the IC designers themselves, who have developed the ICs and also successfully executed several amplifier designs based on them.

When designing a class D amplifier, you typically have two options. You either use a monolithic amplifier IC, which integrates everything except the output filter into one IC.

The advantage typically is the cost and simplicity of the design. However, while monolithic amp IC’s audio performance is usually adequate, it is rarely HI-FI-grade. Furthermore, there are not really any monolithic ICs available above around 200W per channel. The alternative is to design the amplifier using discrete components.

This is usually a much more complex design process, requiring specialist knowledge and IP in class D amplifier technology, as well as much time to fine-tune audio performance, protection mechanisms, etc. The advantage is full flexibility, the ability to design higher power amplifiers, and potentially much better audio quality (if you know what you are doing). 

ICEpower’s class D chipsets represent an alternative that lies somewhere between and offers the best from both worlds. Our chipsets integrate all of the modulation, feedback, monitoring, start-up & shut-down sequencing, protection, etc., but keep the MOSFETs externally. This makes it very easy to scale power and channel counts to the specific application. In fact, our chipset can scale from around 50W all the way to 7kW.

Furthermore, by applying our proprietary modulation and feedback topologies, we are able to create much better audio performance than typical monolithic ICs with much better linearity and lower noise. Whereas monolithic amps typically have noise levels around 100-110dB SNR, we are able to create amplifiers with noise levels down to +130 dB SNR, matching the dynamic range of the very best DA converter ICs on the market. 

Below 100-200W per channel, a monolithic-based amplifier design will typically be cheaper. From around 100-200W, our chipsets can often compete on the cost of the total solution. And above 200-300W there are no monolithic solutions available and we believe our chipsets offer the most cost-effective path, while also providing superlative audio performance.

Product Quality

Our quality is based on our local culture. With the size of Denmark…. or ICEpower…. or any other relevant analogy, our much-valued asset is and can only be our quality. The quality of ICEpower products beats everything. Our first products were available in the year 2001. They are still in use, and they still perform, and we can listen to them every day. Although the consumer electronics industry is characterized by short product life cycles, the audio industry, in general, is characterized by long product lifecycles and making products that last for a lifetime (or almost). 

Many end-users will hang onto their AVR product throughout their life. They will often gladly pay to repair or replace parts if the product fails. In the musical equipment industry, there are many examples of musicians who hold on to a favorite instrument or piece of equipment throughout their entire career because of the unique sound, feel, or sentimental reasons, e.g., being an heirloom.

In the professional audio community, failure during a live event is the worst nightmare. The show must go on, always, no matter the conditions. This underlines how we think quality. Our products must work, and continue to work, for many years, even under harsh circumstances.

Our +1000 years of ICEpower design experience in audio, combined with many proven platforms, have provided us with a thorough understanding of Quality in Audio Products. 

ICEpower only works with high-quality components. We always design with a solid margin concerning component tolerances. 

ICEpower uses a structured approach for design reviews and design verification tests with thorough checklists. We handle all safety and compliance certifications and perform both HALT testing and drop testing on all products to ensure we meet our expectations for performance and reliability.

We conduct reliability testing in a generic and proven test setup. We have full tracking of all products. We work remote yield monitoring, and we have the necessary burn-in capability. Our failure rate has been below 0,3% over the last 10 years.

Working with us means that the ICEpower product maintenance team is your product maintenance team for your products from the cradle to the grave.
