TPS61150DRCT

Overview

The TPS61150DRCT is a dual-output LED lighting driver IC from Texas Instruments, utilizing a boost converter topology. It operates within an input voltage range of 2.5 V to 6 V and delivers up to 700 mA output current per channel. The device features a fixed switching frequency of 1.2 MHz and supports a maximum output voltage of 27 V. Packaged in a VSON-10 (3x3 mm) surface-mount format, it functions across a temperature range of -40°C to +85°C with a maximum supply current of 2 mA.

Feature Summary

• Dual independent current outputs for driving white LEDs
• Integrated high-frequency boost converter switch
• Supports PWM dimming control

Applications

• White LED backlighting systems
• Portable electronic display illumination
• Mobile device LED drivers

Procurement Notes

Verify the specific suffix 'CT' indicates Cut Tape packaging rather than Reel when ordering. Confirm the component matches the VSON-10 package dimensions and pinout requirements for your PCB layout. Ensure the design accommodates the specified thermal operating limits and humidity sensitivity classification during storage and assembly processes.

Selection Notes

Select this component for applications requiring two independently programmable LED channels from a single low-voltage source. The integrated switch reduces external component count compared to discrete solutions. Consider the 1.2 MHz frequency for balancing EMI performance against passive component size constraints in space-sensitive designs.
