A monolithic IC integrates everything except the output filter into one IC. The advantage typically is the cost and simplicity of the design. However, these solutions are typically limited to about 200W max output power. The alternative is to design the amplifier using discrete components such as MOSFETs, gate drivers, comparators, op-amps, etc. The advantage is full flexibility, the ability to design higher power amplifiers, and potentially much better audio quality but higher cost.
ICEpower’s class D chipsets integrate all of the modulation, feedback, monitoring, start-up & shut-down sequencing, protection, etc., but keep the output switching MOSFETs externally. Although this solution generally is more expensive, it can provide better audio performance than typical monolithic ICs with better linearity and lower noise. Furthermore, it is the only solution available for high power amplifiers from 200W up to 7kW output power per channel.
According to ICEpower, the ICC5 builds on the success of its predecessors, the ICCx and ICEedge, catering to cost-sensitive class D audio amplifiers while maintaining the superior audio quality ICEpower is renowned for. This is an avenue that makes increasingly sense for the Danish company, as its business increasingly results from design and engineering services that it provides to brands and manufacturers. The ICC5 solution also is optimized for custom designs and large volume manufacturing, where standard audio amplifier modules make less sense.
Dubbed as a state-of-the-art solution by ICEpower, the new ICC5 chip is a cost-effective solution, while its increased gate drive capability improves efficiency, reducing energy consumption and heat sink requirements. This not only lowers energy costs but also extends the amplifier's lifespan. And the optimized gate drive also improves linearity for higher quality audio performance.
ICEpower's flexible and scalable platforms, coupled with the ICC5, offer a cost-effective alternative to monolithic class D amplifier chips, especially in the 70-100W and above range. This unique combination provides significantly better audio performance, making it suitable for diverse applications, from consumer hi-fi setups to powerful pro audio rack amplifiers and line arrays.
When specifying ICEpower's Audio ICs in their projects, designers gain access to direct support from the company. This support ensures the freedom to create custom designs and leverage existing PCBA manufacturing supply chains, making it an ideal solution for projects with unique requirements or high volumes.
Detailing the key performance metrics for the new ICC5 audio IC, ICEpower highlights the support for up to a 220V supply voltage, which enables class D amplifiers up to 4kW for a Bridge-Tied-Load (BTL) class D amplifier in a 4Ω load. Reported dynamic range SNR is +125dB for a 300W Single Ended reference design (4Ω load), and notable examples of those designs deliver 96% efficiency and 4W idle power consumption.
ICEpower is now accepting orders for the reference design kit, for those that want to start exploring the possibilities with the ICC5. The ICEpower team of experts is ready to support developers throughout the design process.
