TPS61165DBVR in TI TPS6xxxx Bucks & Boosts Family
The TPS61165DBVR family from Texas Instruments consists of high-performance boost converters specifically designed to drive white LEDs in series. Operating from an input voltage range of 3V to 18V, these ICs utilize a high-frequency PWM architecture to provide stable current regulation for backlighting applications. The integrated 40V, 1.2A MOSFET switch allows for driving multiple LEDs with high efficiency, while the compact SOT-23-6 package ensures a minimal footprint in space-constrained embedded designs.
Variants in This Sub-Family
Variants within the TPS6116x sub-family primarily differ in their integrated switch current limits and output voltage ratings. While the TPS61165 provides a 1.2A switch current suitable for larger LED arrays or higher currents, related models like the TPS61160 or TPS61161 offer lower current thresholds (0.7A) for smaller panels. Packaging remains consistent, though some automotive-qualified variants include 'Q1' suffixes to denote AEC-Q100 compliance and enhanced thermal testing.
