1 VDD1 Supply Voltage for Side 1 (3 V to 20 V). Connect a 1 µF capacitor between VDD1 and GND1. 2, 8 GND1 Ground Reference for Side 1. 3 VREG1 Internal Supply Voltage for Side 1. Connect a 1 µF capacitor between VREG1 and GND1. 4 REFOUT1 Reference Output Voltage for Side 1. The maximum recommended capacitance for this pin (CREFOUT1) is 15 pF. 5 NC No Connection. Connect Pin 5 to GND1; do not leave this pin floating. 6 EAOUT2 Isolated Output Voltage 2, Open-Drain Output. Connect a pull-up resistor between EAOUT2 and VDD1 for current up to 1 mA. 7 EAOUT Isolated Output Voltage. 9, 15 GND2 Ground Reference for Side 2. 10 COMP Output of the Op Amp. A loop compensation network can be connected between the COMP pin and the −IN pin. 11 −IN Inverting Op Amp Input. Pin 11 is the connection for the power supply setpoint and compensation network. 12 +IN Noninverting Op Amp Input. Pin 12 can be used as a reference input. 13 REFOUT Reference Output Voltage for Side 2. The maximum recommended capacitance for this pin (CREFOUT) is 15 pF. 14 VREG2 Internal Supply Voltage for Side 2. Connect a 1 µF capacitor between VREG2 and GND2. 16 VDD2 Supply Voltage for Side 2 (3 V to 20 V). Connect a 1 µF capacitor between VDD2 and GND2.
