This reference design offers power for automotive advanced driver assistance systems (ADAS), infotainment and cluster applications. Operation is over the full automotive range including battery voltage surges to 60 V. The design exhibits a peak conversion efficiency of 93% to 96% in the 24-VIN to 48-VIN range. Results demonstrate a 2% output voltage undershoot and overshoot for a 30-A step and dump. The test report includes operational data spanning over the full input range and includes Bode plots to verify stability with ample margins, internal waveforms and thermal images.
