PT4112 Datasheet (PowTech)

PT4112, WLED Driver

The PT4112 is a step-up converter with current sources capable of driving six parallel strings of up to 10 series-connected WLEDs.

Each string is terminated with ballast that achieves ±1.5% current regulation accuracy, ensuring even brightness for all WLEDs.

The PT4112 generates an output voltage to
