CISPR 25 Class 5 Rated Multi-Output Power Supply for Automotive Cluster in Infotainment System
Description
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.
