The QLS30 series uses fewer ponents than any other equivalently rated single board converter. The converters can deliver a maximum of 30 Amps with a typical efficiency of 85%. The QLS provides superior thermal performance, with minimal derating. The QLS30ZB model converter can deliver 22.8 amperes at 1.8 volt output in ambient conditions of 65°C and 200 LFM. This full featured, low profile converter offers input undervoltage lockout, overload, overvoltage and overtemperature protection. Interface Features include remote on/off, remote sense and output voltage trim.
