7 Efficiency Improvement for Different Use Cases

Figure 7-1 demonstrated that enabling the Y-Bridge can lead to a power loss reduction of up to 75% compared to the scenario when absent or not enabled. The degree of power savings can vary depending on the specific use case. For example, audio tracks with silent segments achieve higher power savings than continuous audio tracks, such as music. This substantial reduction in power loss results in an efficiency improvement of 15-20% in lower power modes, when compared to traditional amplifiers that do not utilize the Y-Bridge architecture.
