This reference design provides power for automotive advanced driver assistance systems (ADAS), infotainment, and cluster applications. Operation is over the full automotive range including battery voltage surges to 32 V and dips to 6 V due to cold cranking. The peak conversion efficiency of 94% to 96% in the 10 V_IN to 18 V_IN range is shown. The output voltage undershoot and overshoot are 2% for 30-A step and dump. This test report includes operational data over the full input range and includes Bode plots to verify stability with good margins, internal waveforms, and thermal images.
