Frequently Asked Questions

What is the input voltage range and maximum output current of the TPS628100MQWRWYRQ1?

The TPS628100MQWRWYRQ1 accepts an input voltage from 2.75V to 6V with a nominal input of 5V and delivers up to 4A output current. This makes it suitable for powering microcontrollers and digital logic from standard 5V automotive power rails.

Is the TPS628100MQWRWYRQ1 qualified for automotive use?

Yes, the TPS628100MQWRWYRQ1 carries the AEC-Q100 automotive qualification, making it compliant with strict automotive reliability requirements. It is suitable for use in safety-relevant automotive applications including ADAS, body electronics, and infotainment systems.

What package does the TPS628100MQWRWYRQ1 use and why are wettable flanks important?

The TPS628100MQWRWYRQ1 uses a 2mm x 3mm QFN-9 package with wettable-flanks construction. Wettable flanks allow solder fillet formation on the side of the package terminations, enabling automated optical inspection (AOI) during PCB assembly—a key requirement in automotive production environments.

What control techniques does the TPS628100MQWRWYRQ1 support?

The TPS628100MQWRWYRQ1 supports both PWM (Pulse Width Modulation) in current-mode control for stable high-load regulation and PFM (Pulse Frequency Modulation) for improved light-load efficiency. This dual-mode capability allows it to maintain high efficiency across a wide load range.
