TPS61141DRCR

Overview

The TPS61141DRCR is a dual-output DC-DC boost converter designed for driving white LEDs and OLED backlights. It integrates two internal switches operating at a fixed 1.2MHz frequency, allowing the use of a single inductor to drive two independent channels. The device supports an input voltage range of 2.5V to 6V and delivers up to 35mA per channel with a maximum output voltage of 27V. It features PWM dimming control and operates within a temperature range of -40°C to 85°C.

Feature Summary

Dual-channel architecture utilizing a single inductor for efficient space-constrained designs
Integrated high-frequency switching reduces external component size
Supports precise PWM dimming for backlight brightness control

Applications

White LED backlighting for mobile devices
OLED display driver circuits
Portable electronic equipment power management

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status matches current manufacturing revisions. Ensure the supplier provides official Texas Instruments documentation to validate authenticity. Check moisture sensitivity level handling requirements during storage and assembly processes.

Selection Notes

Select this component when a compact solution for dual LED strings is required. The integrated switch design simplifies bill of materials compared to discrete solutions. Consider the 1.2MHz switching frequency for balancing efficiency and passive component size. Verify that the input voltage range aligns with the system battery profile.

Part Context

This part belongs to the TPS6114x family of LED drivers from Texas Instruments. It is specifically engineered for portable applications requiring high-efficiency power conversion in small footprints. The device complements other PMIC offerings by providing dedicated lighting control capabilities.

Replacement Considerations

The TPS61141DRCRG4 is a verified lead-free variant of the same functional device. Cross-reference pinouts and electrical specifications before substitution to ensure compatibility with existing PCB layouts.
