ABSTRACT:
An amplification device is disclosed providing a way of integrating a switch mode power supply and a class D amplifier (switch mode amplifier). This results in the usage of basically one magnetic component (1), one major energy storage element (4) and switches (20, 30) that are controlled in such a way that both the power supply function and the amplification function are achieved. In this way a cheap, small and highly efficient current configuration is achieved. This amplification device is especially useful in audio products.
