NXP Semiconductors VR5510 Multi-Output PMICs

NXP Semiconductors VR5510 Automotive Multi-Output PMICs are designed for Gateway, ADAS, V2X, and infotainment applications. The VR5510 includes multiple high-efficiency switch modes and linear voltage regulators. The PMICs provide external frequency synchronization on inputs and outputs for optimized system EMC performance.

The NXP Semiconductors VR5510 Automotive Multi-Output PMICs have enhanced safety features with fail-safe outputs and covers ASIL B and ASIL D safety integrity levels. The VR5510 can be fully implemented in a safety-oriented system partitioning and can also be configured to operate as a non-safety QM-version part.

The VR5510 is available in several versions that support various safety applications and present numerous choices for the number of output rails, output voltage settings, operating frequencies, and power-up sequencing.

The VR551 if offered in QFN56 package with thermally enhanced wettable flanks. Devices with wettable flanks enable Automated Optical Inspection (AOI), exhibit a greater resistance to shear forces, and can handle PCB flexing, thus improving reliability.
