... OUT I/O Filtering and Noise Reduction All models in the LSN2-T/30-D12 Series are tested and specifi ed with external 0.01μF, 0.1μF, and 10μF (all paralleled) ceramic/tantalum output capaci- tors and a 22μF tantalum input capacitor. These capacitors are necessary to accommodate our test equipment and may not be required to achieve desired performance in your application. The LSN2-T/30-D12’ ...

... See Typical Performance Curves. Remote Sense LSN2-T/30-D12 Series offer an output sense function. The sense function enables point-of-use regulation for overcoming moderate IR drops in conduc- tors and/or cabling. Since these are non-isolated devices whose inputs and outputs usually share the same ground plane, sense is provided only for the +Output ...

... If the output current exceeds it maximum rating by typically 50 the output voltage drops to less than 98 original value, the LSN2-T/30-D12’s internal overcurrent-detection circuitry immediately turns off the converter, which then goes into a “hiccup” mode. While hiccupping, the converter will continuously attempt to restart itself, go into overcurrent, and then shut down ...

... There are two ways to manage these timing and voltage differences. Either the power up/down sequence can be controlled by discrete On/Off logic controls for each power supply (see Figure 5). Or the power up/down cycle is set by Sequencing or Tracking circuits. Some systems combine both methods. www.murata-ps.com 25 Jun 2010 MDC_LSN2-T/30-D12 email: sales@murata-ps.com Series.B20Δ Page ...

... Lastly, changing the timing may require reprogramming the logic sequencer or rewriting software. Sequence/Track Input A different power sequencing solution is employed on the LSN2-T/30-D12 DC/DC converter. After external input power is applied and the converter stabilizes, a high impedance Sequence/Track input pin accepts an external analog voltage. ...

... Bias source is in fact only a small external bypass capacitor slowly charged by leakage currents. Test your application to be sure. Output Adjustments The LSN2-T/30-D12 series includes a special output voltage trimming feature which is fully compatible with competitive units. The output voltage may be varied using a single trim resistor from the Trim input to Power Common. ...
