A high-voltage boost controller, such as the MAX16990 or the MAX16992, the latter of which has 2.2MHzswitching frequency capabilities, has many applications in the automotive field. Two uses are as a preboostregulator to sustain system voltage during cold-/warm-crank or as a power supply for high-brightness LEDs.In this application note, we begin by examining how to realize an automotive high-voltage step-up DC-DC powersupply with the MAX16990/MAX16992 and how to select the external components to achieve best systemperformance. Afterwards, we present a reference design for its preboost application.
