... LSN2 converters for local 1.8 and 3.3Vdc sup- plies. All system isolation resides in the central supply, leaving lower cost POL regulation at the load. The LSN2’s can deliver very high power (to 52 Watts tiny area without heat sinking or external components. They feature quick transient response (to 25μ ...

... Please refer to the separate LSN2-T/30 data sheet. ➂ These devices have no minimum-load requirements and will regulate under no-load conditions. Regula- tion specifi cations describe the output-voltage deviation as the line voltage or load is varied from its nominal/midpoint value to either extreme. ...

... I/O Filtering and Noise Reduction All models in the LSN2 Series are tested and specifi ed with external 1 || 10μF ceramic/tantalum output capacitors 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 ...

... Input Fusing Most applications and or safety agencies require the installation of fuses at the inputs of power conversion components. The LSN2 Series are not internally fused. Therefore, if input fusing is mandatory, either a normal-blow or a slow-blow fuse with a value no greater than twice the maximum input current calculated at low line with the converter's minimum effi ...

... As you may deduce from the derating curves and observe in the effi ciency curves on the following pages, LSN2 SIPs maintain virtually constant effi cien- cy from half to full load, and consequently deliver very impressive temperature performance even if operating at full load ...

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