Overview
The TPS61041AQDBVRQ1 is an AEC-Q100 qualified boost converter designed for automotive applications. It operates with an input voltage range of 1.8 V to 6 V and delivers a maximum output current of 250 mA. The device features a fixed switching frequency of 1 MHz and supports adjustable output voltages up to 28 V. It includes shutdown functionality and operates within a junction temperature range of -40°C to +125°C. Packaged in a SOT-23-5, it offers low static current consumption.
Feature Summary
- AEC-Q100 qualified for automotive reliability standards
- High-frequency operation at 1 MHz for compact design
- Integrated shutdown control for power management
- Dedicated topology for LCD bias and LED backlight supplies
Applications
- Automotive LCD bias supply circuits
- White LED backlight driver applications
- Small to medium automotive display systems
Procurement Notes
Verify the specific suffix 'AQ' confirms AEC-Q100 qualification and extended temperature range compliance. Ensure the 'RQ1' suffix matches the required tape-and-reel packaging configuration. Cross-reference the datasheet revision against the manufacturing date code to confirm component availability before finalizing procurement plans.
Selection Notes
Select this component when an automotive-grade boost converter is required for LCD or LED backlighting. It is suitable for systems needing a 1.8 V to 6 V input range and up to 250 mA output. Consider the SOT-23-5 package size constraints and the 1 MHz switching frequency requirements for EMI and passive component selection.
Part Context
This part belongs to the TPS6104x-Q1 series of high-frequency boost converters from Texas Instruments. It is specifically engineered for small to medium LCD bias supplies and white LED backlight applications in automotive environments. The series provides a robust solution for step-up conversion needs in constrained spaces.
Replacement Considerations
Consult the official Texas Instruments replacement guide for direct substitutes. Verify that any alternative maintains AEC-Q100 qualification and identical pinout compatibility.
