Product details

Boost regulator for automotive LED strings

It integrates the switching FET internally and delivers up to 38 V from an input supply ranging from 2.7 V to 18 V. Switching at 600 kHz, the part allows small external inductors and capacitors, saving board area in space-constrained modules like infotainment displays or cluster backlights.

This regulator is AEC-Q100 qualified, making it suitable for automotive-grade designs requiring documented reliability screening.

PWM dimming and output current capability

PWM dimming input allows direct brightness control for LED strings, compatible with standard automotive PWM controllers or MCU GPIOs.

Package and footprint for production

Housed in a 6-WDFN exposed-pad package (6-WSON 2x2 mm), the part is surface-mount and requires a thermal pad connection to the PCB ground plane for effective heat dissipation. The small footprint suits automated assembly lines and high-density layouts.

Frequently asked questions

Is TPS61161QDRVRQ1 AEC-Q100 qualified?

Yes, the part is AEC-Q100 qualified, making it suitable for automotive applications requiring documented reliability testing per the AEC-Q100 standard.

Can TPS61161QDRVRQ1 be used as a direct replacement for TPS61161?

The TPS61161QDRVRQ1 is the automotive-qualified variant of the base TPS61161. The base product number is TPS61161, and the QDRVRQ1 suffix indicates AEC-Q100 qualification and the specific package (6-WSON). Pin compatibility depends on the package variant — confirm the footprint matches your board layout before substituting.
