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

... The ULQ Series implements a soft start circuit to limit the duty cycle of its PWM controller at power up, thereby limiting the input inrush current. ...

... 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 ...

... OUT OUT Trimming Output Voltage ULQ converters have a trim capability (pin 6) that enables users to adjust the output voltage from +10% to –20% (refer to the trim equations and trim graphs that follow). Adjustments to the output voltage can be accomplished via a trim pot (Figure single fi xed resistor as shown in Figures 6 and 7. ...

... For the surface mount versions of the ULQ, use the Recommended SMT Pad Layout illustration as a starting point to locate pads to mount the converter. This diagram is for the pads on the mating printed circuit board—it is not the dimensions of the lead terminals on the converter. Note: the pads are slightly larger than the lead terminals to accomodate solder wetting and meniscus ...
