Product Specification
Power Supply Supervisor + Regulator + PWM
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
exists for longer than 7ms, 6105A pulls the PG low and
locks off the power outputs.
Negative Voltage Protection (NVP)
The NVP provides an under-voltage protection (UVP)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
64μA constant current to the negative voltage output. When
the NVP voltage is over 2.1V and the situation kept for
longer than 7ms, 6105A locks the power outputs off:
VNVP = 64μA × (R1 + R2) – V-12V
The power outputs are locked off when VNVP
