Key Design Notes
Resistors R102 and R105 are employed to prevent start-up at low input voltage. After start-up, there is no power
loss in these resistors since the start-up pin is internally disconnected after start-up.
The delay time for overload protection is designed to be about 50ms with C106 of 47nF. If a faster triggering of OLP
is required, C106 can be reduced to 10nF.
Zener diode ZD102 is used for a safety test, such as UL. When the drain pin and feedback pin are shorted, the
zener diode fails and remains short, which causes the fuse (F1) to be blown and prevents explosion of the opto-cou-
pler (IC301). This zener diode also increases the immunity against line surge.
