Typical application circuit
Features
High efficiency (>81% at 85Vac input)
Low zero load power consumption (<300mW at 240Vac input)
Low standby mode power consumption (<800mW at 240Vac input and 0.3W load)
Low component count
Enhanced system reliability through various protection functions
Internal soft-start (10ms)
Key Design Notes
Resistors R102 and R105 are employed to prevent start-up at low input voltage. After startup, there is no power loss in these
resistors since the startup pin is internally disconnected after startup.
The delay time for over load 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 blow and prevents explosion of the opto-coupler (IC301). This zener
diode also increases the immunity against line surges.
