DC/DC Converters come in 36.8 x 58.4 x 10.2 mm package.
Press Release Summary:
With MTBF of 1.4 million hrs, quarter-brick UCQ series includes 24 V input version with 3.3 V, 35 A output; and two 48 V input versions with output of 3.3 V, 30 A and 5 V, 20 A. Synchronous-rectifier topology offers 93% efficiency, line and load regulation down to ±0.2%, 35 mV peak-to-peak noise, and 150 µS step response. Modules operate between -40 and +70ºC with no derating. Full isolation to 2,250 Vdc meets basic requirements of UL/EN/IEC60950.
Original Press Release:
Quarter-brick UCQ Series DC/DC Converters Provide Economical Solution with Outstanding Thermal Performance
o High efficiency single-output DC/DC converters in industry standard package measuring 36.8mm x 58.4mm x 10.2mm
o 20A, 30A and 35A output current versions
o 1.4 million hours MTBF and compliance with agency approvals
August 3rd, 2006, Mansfield, MA - C&D Technologies has introduced a new series of single output, isolated DC/DC converters that combine excellent performance and low cost in applications such as telecom and datacoms equipment, base stations and embedded systems.
The low profile, quarter-brick UCQ series consists of: A 24V input (18-36V range) version with a 3.3V/35A output, and two 48V input (36-75V range) models with outputs of 3.3V/30A and 5V/20A. All have a calculated mean-time-before-failure (MTBF) of 1.4 million hours.
The UCQ's interleaved, synchronous-rectifier topology provides several benefits, including high efficiency (up to 93%), line and load regulation down to ±0.2%, 35mV peak-to-peak noise, no output reverse conduction, and 150µS step response. The single board optimised open-frame design, which measures 36.8mm x 58.4mm x 10.2mm, helps the UCQ series deliver impressive thermal performance; the modules will operate between -40ºC and +70ºC and 100 LFM airflow, with no derating.
The design includes input Pi filters to reduce propagated switching noise back to input sources. Also included is a remote On/Off switch control (with positive or negative polarity), and output trim adjustable from -20% to +10% over nominal and output sense functions to reduce power lead losses. Numerous built-in I/O protection features prevent damage caused by out of limit voltages, currents and temperatures. The modules use the 'hiccup' technique to provide automatic recovery when required.
The UCQ series features full isolation to 2250VDC giving compliance to the (BASIC) requirements of UL/EN/IEC60950. The new DC/DC converters are also Qual/HALT/EMI tested and ULV94-0 rated for flammability.
Unit pricing for the UCQ Series is approximately $41.00 in 1,000 piece quantities, depending on the model, with samples available from stock to 4 weeks.
