Overview

The TPS61041DRVR is a compact, high-frequency boost converter designed for generating output voltages up to 28V from a low-voltage input. Operating with a 1.8V to 6V input range, it is optimized for driving small LCD biases or white LED backlights in battery-powered devices. The device features a low 28uA quiescent current and a shutdown mode that reduces consumption to just 1uA.

Why Choose This Part

The tiny 2mm x 2mm WSON package and high switching frequency (up to 1MHz) minimize the total PCB footprint by allowing the use of small external inductors and capacitors. It offers an internal soft-start function to limit inrush current and maintains high efficiency at light loads due to its low quiescent current.

Applications

LCD Bias Supplies
Generating the high-voltage positive rail required for small monochrome or color LCD panels.
OLED Display Power
Providing stable boosted voltage for small-format OLED displays in wearables and handhelds.
LED Backlighting
Driving series-connected white LEDs for uniform backlighting in portable instruments.

Getting Started

Designers should prioritize a tight layout with short traces for the switch node and feedback path to minimize EMI. Use the TPS61041EVM evaluation module to verify efficiency and ripple performance before integrating into a custom PCB.

Also Consider

TPS61040DBVR TITexas Instruments - Offers a higher 400mA switch current limit compared to the 250mA limit of the TPS61041.
