| Description | 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 re... |
| Features |
to protect itself from fault conditions including built-in open lamp over voltage protection, cycle-by-cycle current limit, over temperature shutdown, input under voltage lock out and integrated soft-start. Additionally, PT4112 provides a driver output for an external PFET connected between the input and inductor. The PFET will be turned off by PT4112 to disconnect the battery from the WLEDs when severe error happens thus any leakage current of the battery is prevented.
