June 2007, Mansfield, MA - C&D Technologies: Today's advanced digital systems demand extended input range compliance on DC/DC power converters. Besides battery and mobile power applications, the ultra wide 4:1 input range of C&D's advanced UQQ family of converters perfectly suits industrial, medical and telecom applications and is capable of supplying up to 100Watts of usable power. Available models are 3.3V/25A, 5V/20A, 12V/8A, 15V/7A and 24V/4A with basic grade I/O isolation voltage of 2250 Volt.

With an overall height of just 0.43" (10.92 mm), the UQQ's readily install on PC boards with half-inch card spacing. Input ranges are 9 to 36 (12V and/or 24Vin nominal) and 18 to 75 Volts DC (24V and/or 48Vin nominal). The UQQ's planar magnetics combined with multilayer heavy copper PC boards and synchronous rectifier topology yield high efficiencies up to 91%.

UQQ system features include undervoltage and overvoltage shutdowns, a Positive or Negative logic-compatible Remote On/Off control, Sense feedback to minimize IR line drop losses and a wide output voltage Trim input to adjust the accuracy. The industry-standard pin-compatible "quarter brick" package measures 2.22 x 1.46 x 0.43 inches (56.4 x 36.8 x 10.92 mm). An optional baseplate maximizes heat transfer to an external mounting surface, giving up to +105 degrees Celsius full power operation. Calculated MTBF figures exceed 5Million hours. All models are fully RoHS-6 hazardous material compliant.

These converters are intended for instruments, mobile battery and vehicle applications, computer systems, medical apparatus, telecommunications and data collection devices.

Unit pricing for 100+ quantities begins at $86.00. Lead-times range from stock to 10-12 weeks.
