Initial Test Set Up
To test the PI2001-EVAL1 evaluation board it is necessary to
configure the jumpers (J1, J2 and J3) first based on the
required board configuration.
Failure to configure the jumpers prior to the testing may
result in improper circuit behavior
Functional Description
VC Bypass Capacitor
Output (Load) Capacitor
Snubber to reduce voltage ringing when the device turns off
To indicate a fault exist when it is on
To select between Master and Slave Modes
Connection between SL1 and SL2
