perfectly. They measure just 1.45 x 2.30 x 0.35 inches (36.8 x 58.4 x 8.9mm) and fit

the industry-standard footprint. You can also "pick-and-place" the ULQ-SMT version

optimizing your automated SMT process.

fully rated at 15 or 25A, 2.5 or 3.3V at 15 or 20A, 5V at 15A and 12V at 8-10A. They

employ an interleaved, synchronous-rectifier topology that exploits 100% of their duty

cycle. They simultaneously achieve ultra-high efficiency (to 91%), tight line/load regu-

lation (±0.125/0.25%), low noise (25-70mVp-p), and quick step response (200µsec).

heavy-copper pc boards all contribute to impressive thermal derating.

... 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 fixed resistor as shown in Figures 6 and 7. ...

Driving the Positive Polarity On/Off Control Pin Surface-Mount Package ("M" suffix) DATEL's ULQ series SMT DC/DC converters are the only higher-power (to 66W) DC/DC's that can be automatically "pick-and-placed" using standard vacuum-pickup equipment and subsequently reflowed using high-tempera- ture, lead-free solder. Virtually all SMT DC/DC's today are unprotected "open-frame" devices assembled by their vendors with high-temperature solder (usually Sn96.5/Ag3.5 with a melting point +221° ...
