PMP9487 is a conducted EMI optimized (CISPR 25) 8W SEPIC converter for wide range Vin automotive infotainment cluster applications using the LM5001 regulator IC (used as SEPIC), LM46002 (used as buck) and LM2831Y regulator IC (used as buck). The design accepts an input voltage of 6.5Vin to 20Vin and provides the outputs of 12V @ 250mA, 3.3V @ 1.2A and 1.8V @ 500mA. It features a small size and is an inexpensive and more efficient solution to using boost converters and linear regulators. Only a single differential filter is used for the complete power tree design in an automotive cluster.
