Class D amplifiers have been used in designs where audio performance and EMI are sacrificed for increased efficiency. Today, however, several new techniques have lead to the introduction of ultra-low ...
Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...
This reference design is for a highly efficient and low-EMI active-clamped forward, 5V powered device (PD). The design features the MAX5969B as its controller. Abstract: This reference design is for a ...
