This reference design provides power for Automotive Advanced Driver Assistance System (ADAS) designs, and infotainment and cluster applications. Operation for automotive applications include battery voltage surges to 32 V and dips to 6 V due to cold cranking. Peak conversion efficiency of 94 % to 96 % in the 10-Vin to 18-Vin range is shown. Output voltage undershoot and overshoot are 2 % for 30-A step and dump. The test report includes operational data over full input range and includes Bode plots to verify stability with good margins, internal waveforms and thermal images.
