NCP1027
The bridge power dissipation is 330 2 /3.018 Meg =
36 mW in nominal high-line operation. Figure 30b
simulation result confirms our calculations.
Figure 31 describes signal variations during a brown-out
when V CC reaches V CC(ON) , ensuring a clean startup
sequence. As in fault mode conditions, the startup source
is activated on and off and self-supplies the controller in a
Dynamic Self-Supply (DSS) mode.
condition. Please note that output pulses only reappear
Figure 31. Signal Evolution During a Brown-Out Condition
Depending on input surge tests, it might be necessary to
wire a filtering capacitor between BO and GND (close to
the circuit) to avoid adversely triggering the internal latch
(unless this is a wanted feature) when the pulse train
appears.
Latchoff Protection
There are some situations where the converter shall be
fully turned-off and stay latched. This can happen in the
presence of a secondary overvoltage (the feedback loop is
drifting) or when an overtemperature is detected.
Secondary monitoring is usually implemented when the
coupling between auxiliary and power windings does not
lead to a precise primary detection, hence the
auto-recovery OVP on pin 1 would not satisfy the precision
requirements. Due to the addition of a comparator on the
BO pin, a simple external circuit can lift up this pin above
VLATCH and permanently disable pulses. The V CC needs
to be cycled down below 3.5 V typically to reset the
controller.
