Power Supply Supervisor + Regulator + PWM
SG6105
PWM switching signal in the secondary power
transformer is proportional to the AC line voltage. Adjust
the ratio of resistor divider to decide the threshold of
power-down warning. A small capacitor is connected
from UVAC to ground for filtering the switching noise.

Over Power Protection (OPP)
The OPP (over power protection) is used for
detecting over power and/or short-circuit conditions.
When OPPS voltage (p.4, Note-1) is higher than 2.1V and
this situation existed for longer than 7 msec, 6105 will
pull the PG low and lock off the power outputs.

Negative Voltage Protection
The NVP provides an UVP (under voltage protection)
for negative voltage outputs. An under-voltage represents
the phenomenal of the overload condition in negative
voltage output. For example, the –12V output may drop
to –10V during the overload situation. A resistor
determining the threshold of the protection is connected
from pin NVP to the negative voltage output. Via this
resistor, NVP outputs a 64uA constant current to the
negative voltage output. When the NVP voltage is over
2.1V and the situation kept for longer than 7 msec, 6105
will lock the power outputs off.
