The Texas Instruments TPS61042DRBT is an inductive step-up (boost) converter designed for LED driver applications, particularly for backlighting. It features a wide input voltage range from 1.8V to 6V and can deliver an output voltage up to 28V.
This device supports precise brightness control using PWM or analog signals and operates at a switching frequency of up to 1MHz. It includes an internal 30V switch capable of handling up to 500mA and offers peak efficiency of 85%. The TPS61042DRBT is designed to work with small output capacitors, down to 100 nF, and includes features like load disconnect during shutdown.
The LED driver is available in a compact 8-SON (3x3) package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The low quiescent current of 38 µA (typical) and shutdown current of 0.1 µA (typical) contribute to power efficiency.
