This reference design offers power for automotive advanced driver assistance systems (ADAS), infotainment, and cluster applications. Operation is over the 24V to 60VDC input range with focus on 48VDC power. Two USB Power Delivery (PD) outputs are provided to allow charging of both a personal computer and smart phone at the same time. The design exhibits a conversion efficiency of 96% for the maximum 60W, 20V, 3A output off 48VIN. The test report includes thermal images, operational data spanning the full input range, and includes output transitions between the four most common output voltages (5V, 9V, 15V and 20V).
