Description
The new QLS30 series of single-output DC/DC converters features single board, multi-layer construction and an SMT design that is highly reliable due to the low component count and minimal manufacturing touch time. The QLS30 series uses fewer components 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.
