Remote switch input for CPU or controller. Control the PWM Output.
3.3V over-voltage/under-voltage control sense input.
5V over-voltage/under-voltage control sense input.
Over-power sense input.
AC fail detection.
The protection input for negative output.
12V over-voltage/under-voltage control sense input.
The totem-pole output drivers of push-pull PWM. The maximum duty
cycle (OP1 or OP2) is 46%.
The totem-pole output drivers of push-pull PWM.
PG logic output, 0 or 1 (open-collector). PG=1 means that the power is
good for operation.
Output of second converter regulation loop.
Reference comparison input for second converter regulation loop. 2.5V.
Reference comparison input for first converter regulation loop. 2.5V.
Output of first converter regulation loop.
Ground.
Error amplifier output and the input of the PWM comparator.
The negative input of error amplifier. The positive input of error amplifier
is connected to 2.5V reference voltage.
The soft-start. It is settable through external capacitor. The current
source output at this pin is 5.7uA and the voltage is clamped at 2.5V.
Connected to external resistor for the reference setting.
Supply voltage. It is connected to 5V-standby.
