Features, Applications


Low cost! Highly reliable! Proven SMT-on-pcb construction Qual tested; HALT tested; EMC tested Designed to meet UL/EN60950 Output voltages: or ±15 Volts Wide input voltage ranges: or 18-75V Small packages, x 0.375" Industry-standard pinouts Fully isolated, 1500Vdc guaranteed Guaranteed efficiencies to +100°C operating temperature Modifications and customs for OEM's

It's hard to beat the combination of low cost, small size (standard x 0.375" package) proven reliability and outstanding electrical performance offered by the 7-10W, dual-output models of DATEL's new A-Series DC/DC converters. These highly efficient, rugged converters combine straightforward circuit topologies, the newest components, proven SMT-on-pcb construction methods, and highly repeatable automatic-assembly techniques. Their superior durability is substantiated by a rigorous in-house qualification program that includes HALT (Highly Accelerated Life Testing). The wide input voltage ranges of these A-Series duals (4.7-7.25V for "D5A" models, 9-18V for "D12A" models and 18-75V for "D48A" models) make them excellent candidates for battery-powered systems or for distributed power architectures. Their or ±15 Volt outputs cover virtually all standard applications. These popular power converters are fully isolated (1500Vdc guaranteed) and display excellent line and load regulation (±0.3% max. for line and ±1% max. for load). They are completely I/O protected (input overvoltage shutdown and reverse-polarity protection, output current limiting and overvoltage protection) and contain input (pi type) and output filtering to reduce noise. They require no external components and offer true "plug-and-play" convenience. These extremely reliable, cost-effective power converters carry industry-standard pinouts making them ideal replacements for other more costly, less reliable power converters in computer, telecom/datacom, instrumentation and ATE applications. They are an excellent choice for both new design-ins and upgrading older systems.

These are stress ratings. Exposure of devices to any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is not implied.

Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Any BWR model may be configured to produce an output or 30V (for or ±15V models, respectively) by applying the load across the +Output and ­Output pins (pins 3 and 5), with either output grounded. The Common pin (pin 4) should be left open. Minimum 20% loading is recommended under these conditions. Filtering and Noise Reduction All A-Series BWR 7-10 Watt DC/DC Converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. In critical applications, input/output ripple and noise may be further reduced by installing electrolytic capacitors across the input terminals and/or low-ESR tantalum or electrolytic capacitors across the output terminals. Output capacitors should be connected between their respective output pin (pin or 5) and Common (pin 4) as shown in Figure 2. The caps should be located as close to the power converters as possible. Typical values are listed in the tables below. In many applications, using values greater than those listed will yield better results.

These power converters require a minimum 20% loading on each output to maintain specified regulation. Operation under no-load conditions will not damage these devices; however they may not meet all listed specifications. Application-specific internal input/output filtering can be recommended or perhaps added internally upon request. Contact DATEL Applications Engineering for details. Devices can be screened or modified for higher guaranteed isolation voltages. Contact DATEL Applications Engineering for details. D5A Models: Zener/transorb only

To Reduce Output Ripple ±5V Output 47µF, 10V, Low ESR ±12/15V Outputs 22µF, 20V, Low ESR In critical, space-sensitive applications, DATEL may be able to tailor the internal input/output filtering of these units to meet your specific requirements.
