GE Energy offers the QBW series of surface mount and through-hole converters, which operate over an input voltage range of 36Vdc to 75Vdc. They provide remote On/Off, output voltage adjustment, remote sense, overvoltage/current protections and overtemperature protection. The QBW018A0B series provide up to 18A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and 12V intermediate bus voltage applications. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 93% at 12V full load. This leads to lower power dissipation such that for many applications a heat sink is not required.
