... You can also "pick-and-place" the ULQ-SMT version optimizing your automated SMT process. From an 18-36V or 36-75V input, ULQ's deliver outputs of 1.2, 1.5, 1. Volts fully rated Amps and 2.5 or 3.3 Volts Amps. They employ an interleaved, synchronous-rectifi er topology that exploits 100% of their duty cycle. ...

... See Output Trimming for detailed trim equations. (9) (10) The Current-Limit Inception point is the output current level at which the ULQ’s power-limiting circuitry drops the output voltage 2% from its initial value. See Output Current Limiting and Short-Circuit Protection for more details. See Performance Curves for additional information. ...

... Nevertheless, if the sense function is not used for remote regulation the user should connect the +Sense to +V DC/DC converter pins. ULQ series converters employ a sense feature to provide point of use regula- tion, thereby overcoming moderate IR drops in pcb conductors or cabling. The remote sense lines carry very little current and therefore require minimal cross-sectional-area conductors ...
