Description
1
MI
Master
Output
SPI Data Output from the Slave MI and SO Line. This pin is paired with SO. On the slave
domain, SO drives this pin.
2
MSS
Master
Input
SPI Slave Select Input from the Master Controller. This pin is paired with SSS. On the slave
domain, this pin drives SSS. This signal uses an active low logic.
3
MGND
Master
Ground
Master Domain Signal Ground Connection.
4
SGND2
Slave
Ground
Slave Domain Ground Connection. This pin can be left unconnected.
5
SGND1
Slave
Ground
Slave Domain SPI Isolator Ground.
6
SSS
Slave
Output
SPI Slave Select Output. This pin is paired with MSS. On the master domain, MSS drives this
pin.
7
SO
Slave
Input
SPI Data Input Going to the Master MI and SO Line. This pin is paired with MI. On the master
domain, this pin drives MI.
8
SI
Slave
Output
SPI Data Output from the Master MO and SI Line. This pin is paired with MO. On the master
domain, MO drives this pin.
9
SCK
Slave
Output
SPI Clock Output from the Master. This pin is paired with MCK. On the master domain, MCK
drives this pin.
10
SVDD1
Slave
Power
SPI Isolator Power Supply. Connect a 100 nF decoupling capacitor from SVDD1 to SGND1.
11
FB3
Slave
Inverting Regulator Feedback Pin.
12
VOUT3
Slave
Power
Inverting Regulator Output and Overvoltage Sense.
13
SW3
Slave
Inverting Regulator Switch Node.
14
SYNC
Slave
Input
Synchronization Pin. To synchronize the switching frequency, connect the SYNC pin to an
external clock at twice the required switching frequency. Do not leave this pin floating. Connect a
100 kΩ pull-down resistor from the SYNC pin to SGND2.
15
VOUT2
Slave
Power
Buck Regulator Output Feedback.
16
SGND2
Slave
Ground
Slave Power Ground. Ground return for inverting and buck regulator output capacitors.
17
SW2
Slave
Buck Regulator Switch Node.
18
VOUT1
Slave
Power
Flyback Regulator Output and Overvoltage Sense. This pin is the input to the buck and inverting
regulators.
19
FB1
Slave
Feedback Node for the Flyback Regulator.
20
SVDD2
Slave
Power
GPIO Isolators Power Supply. Connect a 100 nF decoupling capacitor from SVDD2 to SGND2.
21
SGPI3
Slave
Input
General-Purpose Input 3. This pin is paired with MGPO3.
22
SGPO2
Slave
Output
General-Purpose Output 2. This pin is paired with MGPI2.
