Connect to CS pin of other Z-POLs connected
in parallel
To program the output voltage, connect a
resistor between VREF and TRIM
Connect to SYNC pin of other Z-POLs and/or
to an external clock generator
Connect to OK pin of other Z-1000 POLs.
Leave open, if not used
Polarity is determined by ENP pin
To program the output voltage, connect a
resistor between VREF and TRIM
