Description
I
Remote switch input for CPU or controller. Control the PWM Output.
I
3.3V over-voltage/under-voltage control sense input.
I
5V over-voltage/under-voltage control sense input.
I
Over-power sense input.
I
AC fail detection.
I
The protection input for negative output.
I
12V over-voltage/under-voltage control sense input.
The totem-pole output drivers of push-pull PWM. The maximum duty
O
cycle (OP1 or OP2) is 46%.
O
The totem-pole output drivers of push-pull PWM.
PG logic output, 0 or 1 (open-collector). PG=1 means that the power is
O
good for operation.
O
Output of second converter regulation loop.
I
Reference comparison input for second converter regulation loop. 2.5V.
I
Reference comparison input for first converter regulation loop. 2.5V.
O
Output of first converter regulation loop.
-
Ground.
