... 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 112 Watts tiny area without heat sinking or external components. They feature quick transient response (to 25μ ...

... I/O caps, and will operate within spec in most applications with no additional external components. In particular, the LSN2's input capacitors are specifi ed for low ESR and are fully rated to handle the units' input ripple currents. Similarly, the internal output capacitors are specifi ed for low ESR and full-range frequency response. ...

... 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 inter- nally 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 ...

... High-current-carrying components such as inductors, FET's and diodes are at the highest risk. LSN2 SIP Series DC/DC converters incorporate an output overcurrent detection and shutdown function that serves to protect both the power converter and its load. ...

... The highest temperatures in LSN2 SIPs occur at their output inductor, whose 2 heat is generated primarily losses. The derating curves were developed using thermocouples to monitor the inductor temperature and varying the load to keep that temperature below +110°C under the assorted conditions of air fl ow and air temperature. Once the temperature exceeds +115°C (approx.), the thermal protection will disable the converter. Automatic restart occurs after the temperature has dropped below about +110° ...

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