TPS61041DRVTG4

Overview

The TPS61041DRVTG4 is a high-frequency boost converter designed for small to medium LCD bias and white LED backlight supplies. It operates with an input voltage range of 1.8V to 6V, delivering up to 250mA output current at a maximum voltage of 28V. The device features a fixed switching frequency of 1MHz and low quiescent current of 28uA. Packaged in a compact 6-WSON (2x2) surface-mount format, it supports PWM dimming control for LED applications.

Feature Summary

• Integrated PWM dimming control interface for precise LED brightness adjustment
• High switching frequency operation enabling the use of small external passive components
• Low quiescent current consumption optimized for battery-powered portable devices

Applications

• White LED backlight supplies for mobile phones and handheld devices
• LCD bias voltage generation for portable electronics
• Battery-powered consumer electronic devices requiring efficient step-up conversion

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm package marking and datasheet revision alignment prior to integration. Ensure supply chain documentation matches the specific DRVTG4 suffix requirements for quality assurance and traceability purposes.

Selection Notes

Select this component when a compact solution is required for driving LEDs or biasing LCDs from single-cell lithium-ion batteries. Consider the 6WSON package for space-constrained layouts. Evaluate thermal performance under maximum load conditions and ensure input voltage stays within the specified operational range for stable regulation.

Part Context

This part belongs to the TPS6104x series of low-power DC/DC boost converters. It shares functional similarities with the standard TPS61041 but utilizes a different package configuration. The series is engineered for efficiency and size reduction in portable applications where power management is critical.

Replacement Considerations

The TPS61041DBVR serves as a pin-compatible alternative in a SOT-23-5 package. Verify that the package dimension changes do not impact the PCB layout constraints before substitution.
