Frequently Asked Questions
What input voltage range does the TPS61043DRBT support for LED driving?
The TPS61043DRBT operates from a 2.7 V to 5.5 V input voltage range, making it compatible with single-cell Li-Ion batteries and standard 3.3 V or 5 V regulated rails commonly found in portable and embedded applications.
How many LED channels can the TPS61043DRBT drive simultaneously?
The TPS61043DRBT supports 1 output channel with a constant-current drive of up to 40 mA, making it well suited for single-LED or series-connected LED string backlighting in compact portable devices.
In which compact package is the TPS61043DRBT supplied, and what board area does it occupy?
The TPS61043DRBT comes in an 8-pin DRBT package (SOT-23-style, approximately 3 mm × 3 mm footprint), minimizing PCB area to under 9 mm² and enabling tight placement in space-constrained LED driver layouts.
When would TPS61043DRBT be a better choice than a discrete MOSFET-resistor LED driver?
TPS61043DRBT provides integrated current regulation without a ballast resistor, achieving ±3% current accuracy over the 2.7 V to 5.5 V supply range, which eliminates brightness variation caused by battery droop that affects simple resistor-based solutions.
