ec78ps602a.jpge_arrows.jpg C&D Technology’s UQQ family of converters with a wide 4:1 input range is suited for industrial, medical and telecom applications and is capable of supplying up to 100W of usable power. Available models are 3.3V/25A, 5V/20A, 12V/8A, 15V/7A and 4V/4A with basic grade I/O isolation voltage of 2,250V. With an overall height of 0.43" the UQQs readily install on PCBs with half-inch card spacing. Input ranges are 9V to 36V (12V and 24 Vin nominal) and 18V to 75V DC (24V and/or 48 Vin nominal). The series’ planar magnetics combined with multilayer heavy copper PCBs and synchronous rectifier topology yield high efficiencies up to 91 percent. Features include undervoltage and overvoltage shutdowns, a Positive or Negative logic-compatible On/Off control, sense feedback to minimize IR line drop losses and a wide output voltage Trim input to adjust the accuracy. All models are fully RoHS-6 hazardous material compliant.
