FSCM0565R Fairchild Semiconductor, FSCM0565R Datasheet - Page 13

• Manufacturer Part Number: FSCM0565R
• Description: Green Mode Fairchild Power Switch Fps
• Manufacturer: Fairchild Semiconductor

Typical application circuit
Features
• High efficiency (>81% at 85Vac input)
• Low standby mode power consumption (<1W at 240Vac input and 0.4W load)
• Low component count
• Enhanced system reliability through various protection functions
• Low EMI through frequency modulation
• Internal soft-start (15ms)
Key Design Notes
• The delay time for over load protection is designed to be about 50ms with C106 of 47nF. If a faster triggering of OLP is
• Using a resistor R106 on the current limit pin (#5), the pule-by-pulse current limit level is reduced to about 2A.
• Zener diode ZD102 is used for a safety test such as UL. When the drain pin and feedback pin are shorted, the zener diode

required, C106 can be reduced to 22nF.
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.
