Low-Cost, Wide-Input-Range 12-15 Watt, DC/DC Converters

DATEL’s UER Model single-output switching DC/DC converters were designed for cost-sensitive, moderate-power (12-15 Watts) applications requiring a reliable, off-the shelf solution but not demanding all the high-performance characteristics of DATEL’s A Series UWR Model converters. Offering slightly wider electrical tolerances and slightly lower power densities (8.33W/in3), UER devices achieve their low cost through the use of plastic packaging (UL94V-0 rated material) and the exploitation of traditional, yet highly automated, SMT-on-pcb construction techniques. The result is a contemporary power converter whose cost/performance/reliability ratio far exceeds the competition.
UER Model DC/DC converters offer the ultra-wide, 9-to-36V and 18-to-72V, input voltage ranges that have come to be associated with DATEL power converters. Output voltages are 3.3V, 5V, 12V or 15V. Line and load regulation are both guaranteed not to exceed ±1%. All models incorporate internal input/output filtering and require no external components for normal operation. All units guarantee output ripple/noise less than 100mVp-p.
