TPS61043DRB Description

Short technical summary and product information.

The Texas Instruments TPS61043DRB is a high-frequency boost converter that functions as a constant current LED driver. It is designed to drive white LEDs or similar applications, capable of powering up to 4 LEDs in series. The device operates with an input voltage range from 1.8 V to 6.0 V and features an internal 400 mA switch.

 

Key features include precise brightness control using PWM or analog signals, with a PWM frequency range of 100 Hz to 50 kHz. The LED current is set by an external sense resistor and regulated by the feedback pin. For safety during operation, the output includes integrated overvoltage protection, limiting the output voltage to typically 18 V in case of a high impedance output.

 

The TPS61043DRB is available in a compact 3 mm x 3 mm QFN package, making it suitable for space-constrained designs. It offers up to 85% efficiency and disconnects LEDs during shutdown to prevent leakage currents. The no-load quiescent current is typically 38 µA, and shutdown current is typically 0.1 µA.
