TPS61193PWPR in TI TPS6xxxx Bucks & Boosts Family
The TPS61193PWPR belongs to a specialized family of high-efficiency automotive LED drivers from Texas Instruments. Designed primarily for LCD backlighting, these 4-channel boost controllers integrate a DC-DC converter with current sinks to provide uniform illumination. They are engineered for demanding environments where electromagnetic interference (EMI) mitigation and thermal reliability are critical, ensuring stable operation across wide input voltage ranges while maintaining precise current matching for high-quality display performance.
Variants in This Sub-Family
Variants within the TPS61193 sub-family typically differ by their automotive qualification status (Q1 grade) and packaging options like HTSSOP or VQFN. Some iterations may offer variations in the maximum current per channel—typically up to 100mA—or specialized protection thresholds. Designers should verify the specific I2C programmability or fixed-function pin configurations required for their target application when selecting between members.
