TPS61040DRVT

Overview

The TPS61040DRVT is a high-frequency boost converter from Texas Instruments, designed for small to medium LCD bias supplies and white LED backlight applications. It operates with an input voltage range of 1.8V to 6V and provides a regulated output voltage adjustable from 1.8V to 28V. The device delivers a maximum output current of 400mA with a switching frequency up to 1MHz. It features a low operating supply current of 28µA and functions within a temperature range of -40°C to +85°C. The component is housed in a compact 6-WSON (2x2mm) package with exposed pad.

Feature Summary

• Integrated synchronous boost topology for efficient power conversion
• Adjustable output voltage capability supporting diverse load requirements
• Low quiescent current consumption for extended battery life
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• White LED backlight drivers
• LCD bias supply generation
• Portable electronic devices requiring step-up regulation

Procurement Notes

Verify the specific suffix DRVT corresponds to the 6-WSON package and reel/cut-tape availability. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a compact boost converter is needed for LED or LCD applications. Consider the 400mA output limit and 28V maximum output voltage. Evaluate thermal performance due to the small WSON footprint. Compare against other TPS6104x variants if different pinouts or packages are required.

Part Context

This device belongs to the TPS6104x series of switch boost converters. It shares functional similarities with the TPS61041 but may differ in pin configuration or specific electrical characteristics. The series is optimized for portable electronics where size and efficiency are critical constraints.

Replacement Considerations

Check for direct substitutes within the TPS6104x family. Verify pin compatibility and electrical parameters before replacing. Consult official substitution guides for cross-references.
