Frequently Asked Questions
What output voltage does the TPS62850220QDRLRQ1 provide and what input range does it accept?
The TPS62850220QDRLRQ1 is a fixed-output step-down converter set to 2.2 V, operating from a 2.7 V to 6 V input supply with a nominal design point of 5 V, making it well-suited for powering 2.2 V logic rails in automotive infotainment and ADAS sensor systems.
How does the PWM/PFM dual-mode control improve efficiency in automotive applications?
The TPS62850220QDRLRQ1 automatically switches between pulse-width modulation at heavy loads up to 2 A and pulse-frequency modulation at light loads, maintaining high conversion efficiency across the full current range and reducing quiescent current draw in always-on automotive subsystems to minimize battery drain.
What does the automotive qualification of the TPS62850220QDRLRQ1 imply for reliability?
The Q1 suffix denotes AEC-Q100 automotive qualification, meaning the TPS62850220QDRLRQ1 has been tested and qualified for reliability across automotive operating conditions including extended temperature ranges typically from -40°C to +125°C, as required for ECUs, telematics modules, and dashboard electronics in production vehicles.
How small is the TPS62850220QDRLRQ1 package and why does it matter for dense automotive PCBs?
The TPS62850220QDRLRQ1 uses an 8-pin SOT583 flat-lead package (R-PDSO-F8) with an extremely small footprint of approximately 2 mm × 2 mm, enabling a complete 2 A step-down power stage with minimal external components on tightly packed automotive ECU and ADAS sensor boards.
