... SIMPLIFIED SCHEMATIC Typical topology is shown. UQQ Series The UQQ's feature set includes high isolation, input pi filters, input undervoltage shutdown, output overvoltage protection, current limiting, short-cir- cuit protection and thermal shutdown. The standard footprint carries on/off control (positive or negative polarity), output trim (+0/– ...

... The UQQ series may include an optional installed baseplate for extended thermal management. This baseplate is electrically isolated from the rest of the con- verter. Various UQQ models are also available with an additional pin 9 on special quantity order which electrically connects to the baseplate. Pin 9 is also isolated from the rest of the converter ...

... Table is not implied nor recommended Removal of Soldered UQQ's from Printed Circuit Boards Should removal of the UQQ from its soldered connection be needed, thor- oughly de-solder the pins using solder wicks or de-soldering tools time should any prying or leverage be used to remove boards that have not been properly de-soldered first ...

... This on/off cycling is referred to as “hiccup” mode. The hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels. The UQQ is capable of enduring an indefinite short circuit output condition. Thermal Shutdown UQQ converters are equipped with thermal-shutdown circuitry ...

... Trimming Output Voltage UQQ converters have a trim capability (pin 6) that enables users to adjust the output voltage from +0% to –20% (refer to the trim equations). Adjustments to the output voltage can be accomplished with a single fixed resistor as shown in Figures 5 and 6 ...

... UQQ Series Aluminum Heatsink Please note – The UQQ series shares the same heatsink kits as the UVQ series. Therefore, when ordering these heat sinks, use the model numbers below which end with the ‘UVQ’ suffix. The UQQ series converter baseplate can be attached either to an enclosure wall or a heatsink to remove heat from internal power dissipation ...
