This automotive pre-regulator reference design showcases a nonsynchronous single-ended primary-inductor converter (SEPIC), which covers an input voltage range of 6.0 V to 36 V. The output voltage is 12.0 V with a maximum load current of 2.0 A. The design can operate down to an input voltage of 4.5 V to support automotive cranking.
