PMP4442-4, Automotive I.MX6 Quad Core Processor Power Solution Reference Design

PMP4442-4, Automotive I.MX6 Quad Core Processor Power Solution Reference Design. This design is an low-cost discrete power solution to power I.MX6 quad core. All the DCDC regulators are running at 2MHz to avoid the AM band interference and provide low solution size. The first stage DCDC converter can support wide Vin range from 6V to 42V, which can support start-stop system as well as load dump. The second stage DCDC provides all the necessary power rails to power up I.MX6 quad core. I.MX6 is very loose on the power sequencing of the different rails so no sequencer is necessary for this design. It uses a 4 layer board with 2oz copper to have better thermal characteristic at 2MHz switching frequency and 85C ambient
