TPS61041DBVR

Overview

The TPS61041DBVR is a high-frequency boost converter from Texas Instruments, designed for small to medium LCD bias and white LED backlight supplies. It operates with an input voltage range of 1.8 V to 6 V and provides a maximum output voltage of 28 V. The device supports a continuous output current of 250 mA. It features a switching frequency range of 50 kHz to 1 MHz and maintains a typical quiescent current of 28 uA. Packaged in a SOT-23-5 (SC-74A) surface-mount case, it functions within a temperature range of -40°C to 85°C.

Feature Summary

Integrated high-frequency boost converter topology optimized for compact power solutions
Low quiescent current operation to extend battery life in portable applications
Adjustable output voltage capability up to 28 V for flexible system design

Applications

White LED backlight supplies
Small to medium LCD bias supply circuits
Portable electronic devices requiring efficient DC-DC conversion

Procurement Notes

Verify the specific suffix 'DBVR' corresponds to the SOT-23-5 package and reel tape quantity when ordering. Confirm that the standard commercial grade (-40°C to 85°C) meets your environmental requirements, as automotive variants carry distinct Q1 suffixes. Ensure compatibility with existing PCB footprints for SC-74A packages during component sourcing.

Selection Notes

Select this component for designs requiring a compact boost solution with low standby current. It is suitable for single-cell lithium-ion battery applications given the 1.8 V minimum input. Consider the 250 mA output limit for load requirements. For automotive use cases, verify if the AEC-Q100 qualified TPS61041QDBVRQ1 is required instead.

Part Context

This part belongs to the TPS6104x series of high-frequency boost converters. It shares architectural similarities with the TPS61040 but differs in output current specifications. The series is engineered for space-constrained applications, offering a balance between efficiency and physical size through its integrated switch and control logic.
