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
• The delay time for over load protection is designed to be about 50ms with C106 of 47nF. If a faster triggering of OLP is
• 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) blown and prevents explosion of the opto-coupler (IC301). This zener
diode also increases the immunity against line surge.
