PT4112 Overview
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 drive up to totally 60 WLEDs from a 5V to 25V input source;.
