CISPR 25 Class 5: 3-W SEPIC reference design for automotive infotainment display power
Description
PMP9481 is a conducted EMI optimized (CISPR 25 Class 5) 3W SEPIC converter for wide range Vin automotive applications using the LM5001 regulator IC. The design accepts an input voltage of 6.5Vin to 20Vin and provides an output of 12Vout capable of supplying 0.25A of current to the load. This design features the LM5001 boost controller available in automotive grade versions and qualified in AEC-Q100 Grade 1. LM5001 has a very wide Vin range of 3.1V to 75V and hence is input transient protected. The board layout is optimized for improved conducted EMI performance. The board is tested under the automotive EMC standard: CISPR 25: and its conducted emissions are in compliance with the CISPR 25 Class 5 requirements.
Features
