Description
The QW series power modules are isolated dc-dc converters that can deliver up to 20A of output current and provide a pre-
cisely regulated output voltage over a wide range of input voltages (VI = 36Vdc to 75Vdc). The modules achieve full load effi-
ciency of 91% at 3.3V output voltage, The open frame modules, available in both surface-mount and through-hole packaging,
enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, output voltage adjust-
ment, remote sense,overvoltage, overcurrent and overtemperature protection.
