Pin No. Mnemonic Description
1
VDD1
Supply Voltage for Side 1 (3.0 V to 20 V). Connect a 1 μF capacitor between VDD1 and GND1.
2
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 capacitance for this pin (CREFOUT1) must not exceed 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.
8
GND1
Ground Reference for Side 1.
9
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 capacitance for this pin (CREFOUT) must not exceed 15 pF.
14
VREG2
Internal Supply Voltage for Side 2. Connect a 1 μF capacitor between VREG2 and GND2.
15
GND2
Ground Reference for Side 2.
16
VDD2
Supply Voltage for Side 2 (3.0 V to 20 V). Connect a 1 μF capacitor between VDD2 and GND2.
