C&D Tech Adds 4:1 Wide Input, 100W Quarter Brick DC-DC Converters

C&D Technologies announced its UQQ family of dc-dc converters. 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 UQQ family of converters are claimed by the company to "perfectly suit" 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 24V/4A with basic grade I/O isolation voltage of 2250V.

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 75Vdc (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°C full power operation. Calculated MTBF figures exceed 5 million 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.
