... For On/Off Control on negative-polarity UQQ-3.3/25-Q48N models, the maximum OFF mode control voltage is +13.5 Volts. For the ON mode, the range is pin grounded to +1 Volt max. (17) Always connect the sense pins. If they are not connected to a remote load, connect each sense pin to its respective output at the converter pins ...

... DC/DC converter. I/O Filtering, Input Ripple Current, and Output Noise All models in the UQQ Series are tested/specifi ed for input ripple current (also called input refl ected ripple current) and output noise using the circuits and layout shown in Figures 2 and 3. External input capacitors (C serve primarily as energy-storage elements ...

... 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 indefi nite 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 +10% to –20% (refer to the trim equations). Adjustments to the output voltage can be accomplished with a single fi xed resistor as shown in Figures 5 and 6. A single fi ...

... 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’ suffi x. The UQQ series converter baseplate can be attached either to an enclosure wall or a heatsink to remove heat from internal power dissipation ...

... Kit includes heatsink, thermal pad and mounting hardware. These are non-RoHS models. For RoHS-6 versions, add “-C” to the model number (e.g., HS-QB25-UVQ-C). These model numbers are correct for the UQQ series. Heat Sink Example Assume an effi ciency of 92% and power output of 100 Watts. Using equation [4 about 8.7 Watts at an input voltage of 48 Volts. Using +30° ...

... Both sides of the UUT are studied since there are different thermal gradients on each side. The adjustable heating element and fan, built-in temperature gauges and no-contact IR camera mean that power supplies are tested in real-world conditions. 22 Feb 2011 MDC_UQQ.A15 Page UQQ Series email: sales@murata-ps.com ...
