MECHANICAL DATA Figure 1. Package R; dimensions in mm (inches) PIN DESCRIPTION Pin Function Description 1 ENABLE The converter is ON (Enable) when the voltage applied to this pin with reference to pin 2 is lower than 1.2V. The converter is OFF (Inhibit) for a control voltage in the range of 2.1 to 5V. When the pin is unconnected the converter is OFF (Inhibit). 2 - Vin Negative input voltage. 3 + Vin Positive input voltage. Unregulated input voltage in the range of 200 to 400Vdc must be applied between pin 2-3. 4,5 + Vo +Vo output voltage. 6,7 - Vo +Vo output voltage return. 8 + SENSE Senses the remote load high side. To be connected to pins 4,5 when remote sense is not used. 9 - SENSE Senses the remote load return. To be connected to pins 6,7 when remote sense is not used. 10 ADJ 8/10 Adjust output voltage pin. A voltage generator between the ADJ. pin and -SENSE pin sets the Vo. When unconnected Vo is at nominal value (see fig. 2).
