TPS61041DRVR

Overview

The TPS61041DRVR 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 1.8 V to 6 V and provides a regulated output voltage adjustable from 1.8 V to 28 V. The device delivers a maximum output current of 250 mA. It features a switching frequency range of 50 kHz to 1 MHz and functions within an operating temperature range of -40°C to +85°C. The component is housed in a WSON-6 package.

Feature Summary

• Integrated synchronous rectification for improved efficiency in compact designs
• Fixed switching frequency operation enabling the use of small external components
• Low quiescent current consumption to extend battery life in portable devices

Applications

• LCD bias supply for small to medium displays
• White LED backlight power sources
• Portable electronic devices requiring efficient step-up conversion

Procurement Notes

Verify the specific suffix DRVR corresponds to the WSON-6 package and tape-and-reel packaging configuration required for your assembly process. Confirm that the thermal performance specifications align with your board layout and ambient operating conditions. Ensure compatibility with your manufacturing equipment for surface-mount placement on the specified footprint.

Selection Notes

Select this component when a compact solution is needed for boosting low input voltages to higher levels for display or lighting loads. Consider the 250 mA output limit and the WSON-6 thermal characteristics against your power requirements. Evaluate the fixed frequency operation against noise sensitivity constraints in your system design compared to variable frequency alternatives.

Part Context

This part belongs to the TPS6104x family of low-power DC/DC boost converters. The family includes variants such as the TPS61040 and TPS61041, which share similar functional architectures but may differ in output current capabilities or package options. The TPS61041 specifically targets applications requiring up to 250 mA output current.

Replacement Considerations

Direct substitutes include other parts within the TPS6104x family, such as the TPS61040 series, provided the output current and package differences are acceptable. Verify pinout compatibility and electrical parameters before swapping to ensure circuit functionality remains intact.
