... 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 (“ ...

... 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/° ...
