Overview
The TPS61161QDRVRQ1 is an automotive-grade boost converter designed for white LED lighting applications. It features a 40-V rated integrated switch FET and supports driving up to 10 LEDs in series. The device operates with an input voltage range of 2.7 V to 18 V and delivers a maximum output current of 700 mA at a fixed switching frequency of 600 kHz. It achieves a maximum output voltage of 38 V and functions within a temperature range of -40°C to +125°C. Packaged in a compact 6-WSON (2x2 mm) format, it meets AEC-Q100 qualification standards.
Feature Summary
- Integrates a 40-V rated power switch for high-voltage LED string driving
- Supports digital and PWM brightness control interfaces
- Includes open LED protection for system reliability
- Automotive qualified under AEC-Q100 standards
Applications
- Automotive exterior white LED lighting modules
- High-brightness LED arrays requiring series configuration
- Vehicle interior ambient lighting systems
Procurement Notes
Verify the specific suffix 'QDRVRQ1' confirms AEC-Q100 automotive qualification and the 125°C operating range. Ensure the order matches the WSON-6 package variant. Confirm that the application requires the 700 mA switch current limit and 600 kHz frequency. Cross-reference the datasheet revision date against production timelines to ensure component availability aligns with manufacturing schedules.
Selection Notes
Select this component when designing automotive lighting circuits requiring a single-channel boost topology with integrated power switching. It is suitable for applications needing precise PWM dimming and digital control inputs. Consider the 2.7 V to 18 V input range compatibility with vehicle battery systems. Evaluate the thermal performance requirements given the 125°C junction temperature capability and small form factor constraints.
Part Context
This part belongs to the Texas Instruments TPS61161 family of white LED drivers. It shares functional similarities with the non-automotive TPS61161DRVR but includes extended temperature ratings and automotive reliability testing. The Q1 designation indicates compliance with automotive quality standards, distinguishing it from commercial grade variants in the same series.
Replacement Considerations
The TPS61161DRVR is a commercial equivalent but lacks automotive qualification and the extended temperature range. Verify if the application strictly requires AEC-Q100 certification before substituting.
