TPS61151DRCT

Overview

The TPS61151DRCT is a dual-output LED lighting driver IC from Texas Instruments, featuring a 1.2 MHz boost converter topology. It supports an input voltage range of 2.5 V to 6 V and delivers up to 700 mA output current per channel. The device operates with a maximum output voltage of 27 V and functions within a temperature range of -40°C to +85°C. Packaged in a compact VSON-10 (3x3 mm) footprint, it integrates PWM dimming capabilities for precise control in white LED applications.

Feature Summary

• Dual independent output channels for flexible LED string configuration
• Integrated 1.2 MHz switching frequency for reduced external component size
• Supports PWM dimming for high-contrast brightness control
• Compact VSON-10 package optimized for space-constrained designs

Applications

• White LED backlighting systems
• Portable electronic device illumination
• Automotive interior lighting modules
• General-purpose LED driver circuits

Procurement Notes

Verify the specific suffix 'DRCT' corresponds to the cut-tape packaging variant when ordering. Confirm that the VSON-10 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the operating temperature range of -40°C to +85°C. Cross-reference the datasheet for any recent design revisions or recommended layout guidelines to ensure optimal performance.

Selection Notes

Select this component for applications requiring dual-channel LED drive with integrated boost conversion. The 1.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 700 mA current limit when sizing LED strings. The VSON-10 package offers a balance between thermal dissipation and board space efficiency for portable devices.

Part Context

This part belongs to the TPS61150 series of LED drivers, designed specifically for white LED applications. It shares architectural similarities with the TPS61150 but includes specific enhancements for dual-output operation. The series is characterized by its high integration level, combining power switches and control logic in a single small package.

Replacement Considerations

The TPS61150DRCT is a related single-output variant within the same family. Verify if single-channel operation suffices before substituting. No direct pin-to-pin replacements are confirmed in public documentation; consult TI for qualified alternatives.
