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 PD outputs are provided, to allow charging of various high-power devices. The design exhibits conversion efficiency of 98.1% for the maximum 180W 36V 5A output off 48Vin. The test report includes operational data spanning over the full input range and includes output transitions between 5Vout and 36Vout to show the worst-case scenarios. Thermal images at 180W out and voltage ripple are also showcased in this test report. This reference design is the extended power range version of the PMP23501 board.
