... Dynamic control of the remote on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). The drive circuit should be able to sink appropriate current (see Performance Specifi cations) when activated and withstand appropriate voltage when deactivated. Figure 4. Driving the Remote On/Off Control Pin ...

Input Reverse-Polarity Protection If the input-voltage polarity is accidentally reversed, an internal diode will become forward biased and likely draw excessive current from the power source. If the source is not current limited or the circuit appropriately fused, it could ...

... The discussion below concerns only the heatsink alternative. The UQQ’s are available with a low-profi le extruded aluminum heatsink kit, models HS-QB25-UVQ, HS-QB50-UVQ, and HS-QB100-UVQ. This kit includes the heatsink, thermal mounting pad, screws and mounting hardware. See the assembly diagram below. Do not overtighten the screws in the tapped holes in the converter. This kit adds excellent thermal performance without sacrifi ...

... Under Test (UUT) with both dynamic loads and static steady- state conditions. A special optical port is used which is transpar- ent to infrared wavelengths. The computer fi les from the IR camera can be studied for later analysis. Both through-hole and surface mount converters are soldered down to a host carrier board for realistic heat absorption and spreading. Both longitudinal and transverse airfl ...
