... Single Output, High-Density, 3.3V PRODUCT OVERVIEW The newest products in DATEL’s flagship A-Series are the UWR, 26-40 Watt isolated singles. Housed in standard 2" x 2" metal packages (which have traditionally carried 15-20 Watt devices), these power converters supply Amps @ 3. Amps at 5V. They exemplify DATEL’s relentless drive to bring designers more power/current, in standard packages/pinouts, without compromising reliability or resorting to thermal specmanship. Input voltage ranges are 10-18V (“ ...

... UWR-3.3/9-D48AN-C 3.3 9 UWR-5/7-D12A UWR-5/8-D24A UWR-5/8-D48AN Typical +25°C under nominal line voltage and full-load conditions, unless noted. Ripple/Noise (R/N) is tested/speciifed over a 20MHz bandwidth. All models are specified with an external 0.47μF multi-layer ceramic capacitor installed across their output pins. Using a 10μF multi-layer ceramic capacitor instead (e.g. TDK part no. C3225X5R1C106M) will further reduce the R/N to 35mVp-p typical and 75mVp-p maximum. Load regulation is specifi ...

... All models regulate within spec and are stable under no-load conditions. Filtering and Noise Reduction All UWR 26-40 Watt DC/DC Converters achieve their rated ripple and noise specifications using the external output capacitor specified in the Perfor- mance/Functional Specifications table. In critical applications, input/output noise may be further reduced by installing additional external I/O caps ...

... Actual measured times will vary with input source impedance, external input/output capaci- tance, and load. The UWR 26-40 Watt implements a soft start circuit that limits the duty cycle of the PWM controller at power up, thereby limiting the Input Inrush current ...

... Trimming Output Voltage UWR 26-40W converters have a trim capability (pin 8) that allows users to adjust the output voltages ±5%. Adjustments to the output voltages can be accomplished via a trim pot (Figure single fixed resistor as shown in Figures 6 and 7. A single fixed resistor can increase or decrease the output voltage depending on its connection. Resistors should be located close to the converter and have TCR's less than 100ppm/° ...
