To increase UVLO connect a resistor between pin 11 (Vin-) and pin 12 (UV/REM). Pin 12 must never be connected directly to voltages higher than 7VDC. The same pin operates Remote ON/OFF. The UV/REM pin (pin 12) is internally pulled higher than the Remote on threshold. To turn the unit off use an open collector driver to pull the pin lower than the minimum Remote ON threshold by at least the maximum remote ON/OFF hysteresis. See Application Note for specific details. 3V3, 5V: Max. capacitive load is limited to 2200µF per rated output Amp to guarantee recovery from overload, @ 75Vin and max. temperature operation. For operation at Vin <65VDC and <70°C ambient; there is no restriction on load capacitance. 12V: See Application Note for more details. Start-up into RC loads is dependant on input voltage and load characteristics at high ambient temperatures. Note 6 Thermal hot spot is the temperature of the main output diode tab, as shown in Figure 7. This is the optimum measurement point for thermal design considerations when integrating the SXA10 into a system. The tab is at DC potential and may be used with an isolated thermocouple instrument. For a maximally configured system and least airflow, this temperature should stabilise to be less than 110°C. Pin 3 can also be used for thermal hot spot measurements, however its maximum temperature should be less than 95°C. D-PAK TAB = Thermal Hot Spot 1 Note 2 Operational Insulation, as defined by CSA 22.2 No 950, UL1950 and EN 60950, is designed into this component. The unit is classified for Pollution Degree 2 Environment. Unit top surface is exposed at input voltage potential and will have same category insulation as input. The unit is designed for ‘service access’ or ‘restricted access’ as defined by CSA C22.2 No 950, UL1950. Figure 7 - Thermal Hot Spot This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Note 3 For applications with input voltages between 36 and 75V, and operating ambient temperatures of -10C to 70C the device will deliver an extra 10% output power. The device will continue to meet all specifications listed in this data sheet. Refer to Figure 5.

The units have reduced mass to reduce transportation costs. No encapsulation epoxies are used. The substrate, being ceramic with copper conductors and with only 0.1mm silver pad plating, is environmentally benign. The SnAg component and lead attach solder alloy has 0% lead present. The packaging trays are designed to be both reusable and recyclable. Figure 9 - Dimensioned Product View PAGE 5 Seating Plane For operation at >70% of nominal output current and at <29VDC in; an external series line dampening resistor should be employed. A 0.39Ω resistor should be fitted in series with Vin+. A 1210 package size should be used. The recommended resistor is from KOA; SR73K2ETRDR39F.
