LM3555TLX/NOPB TI LED Driver | 12-DSBGA | 2.5V-5.5V, 1.5A

Product Overview

The LM3555TLX/NOPB is a high-power, synchronous boost converter with an integrated 1.5A switch, designed to drive up to 10 series white LEDs or provide a constant voltage output. It operates from a single-cell Li-Ion battery or fixed 2.5V to 5.5V input, delivering up to 90% efficiency. The device features a 1.2MHz fixed switching frequency, enabling small external components. Housed in a compact 12-DSBGA package (2.0mm x 2.0mm), it is ideal for space-constrained portable applications.
