Frequently Asked Questions
What output current capability does the TPS65919-Q1 support for processor power rails?
The TPS65919-Q1 supports up to 5 A output current on its DC-DC converter channels, providing sufficient power for high-performance application processors. Its multiple rails can be programmed from 0.5 V to 3.3 V to match processor core and I/O voltage requirements. This makes it suitable for automotive SoCs requiring precise, high-current power delivery.
Which automotive safety standard qualifies the TPS65919-Q1, and what temperature range does it cover?
The TPS65919-Q1 is qualified to AEC-Q100 Grade 1, the automotive IC reliability standard covering a junction temperature range of -40°C to 125°C. This qualification ensures the device meets stringent automotive reliability requirements for under-hood and cockpit applications. The wide temperature range enables deployment in infotainment systems, ADAS controllers, and instrument clusters.
How does the TPS65919-Q1 handle power sequencing for multi-core processors in automotive designs?
The TPS65919-Q1 integrates programmable power sequencing that manages the turn-on and turn-off order of multiple voltage rails, which is critical for multi-core processors with strict sequencing requirements. It supports configurable timing delays between rails to prevent latch-up conditions. This built-in sequencing reduces external logic requirements and simplifies board design for automotive applications.
When should a designer choose TPS65919-Q1 over discrete regulators for automotive processor power supply?
TPS65919-Q1 is the preferred solution when a design requires 5 or more regulated voltage rails in a compact footprint, as integrating multiple converters saves significant PCB area compared to discrete regulators. The device delivers programmable rails from 0.5 V to 3.3 V with fault monitoring, removing the need for external supervisors. For AEC-Q100 Grade 1 automotive projects, the single-component solution also simplifies qualification testing.
