TPS61041DRVT

Overview

The TPS61041DRVT 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 maximum output voltage of 28V at 250mA. The device features a switching frequency between 50kHz and 1MHz. It is housed in a 6-pin WSON (DRV) package with dimensions of 2x2mm. The operational temperature range spans from -40°C to 85°C.

Feature Summary

• Dedicated topology for LCD bias and white LED backlight power generation
• High-frequency operation enabling compact external component sizing
• Integrated synchronous rectification for improved efficiency

Applications

• LCD bias supply circuits
• White LED backlight drivers
• Portable electronic devices requiring step-up conversion

Procurement Notes

Verify the specific suffix DRVT corresponds to the 6-WDFN package and tape-and-reel shipping configuration. Confirm that the automotive qualification suffix QDBVRQ1 is not required if the application does not demand AEC-Q100 compliance. Ensure the design accounts for the specified thermal performance within the -40°C to 85°C operating range.

Selection Notes

Select this component when a low-power boost converter is needed for LED or LCD applications with an input source between 1.8V and 6V. The fixed 250mA output current limit suits small displays. Consider the WSON package for space-constrained PCB layouts. Verify that the 28V maximum output voltage meets the load requirements without exceeding component ratings.

Part Context

This part belongs to the TPS6104x series of low-power DC/DC boost converters. The series includes variants such as the TPS61040 and TPS61041, differentiated by specific electrical characteristics. The DRVT suffix indicates the specific tape-and-reel packaging format used for automated assembly processes.
