This reference design provides protection and power for automotive audio systems. Operation with a 48VDC input was tested across the full output voltage range: 6VDC to 35VDC. The design exhibits a peak efficiency of 97% at nominal load, and no significant output voltage undershoot and overshoot for loaded transitions between 6VDC and 35VDC. This test report includes operational data spanning the output voltage range and load, including bode plots, switching waveforms, load transient responses, start-up and shutdown waveforms, and thermal images.
