• Manufacturer Part Number: FSDH0265RN_05
• Description: Green Mode Fairchild Power Switch (FPSTM)
• Manufacturer: FAIRCHILD [Fairchild Semiconductor]

FSDH0265RN, FSDM0265RN
Typical Application Circuit
Features
• High efficiency (>76% at universal input)
• Low standby mode power consumption (<1W at 230Vac input and 0.5W 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 30ms with C106 of 47nF. If faster/slower triggering of OLP
• Using a resistor R104(3.3㏀) on Ipk pin (#4), the pule-by-pulse peak current limit level(I
• The branch formed by D103, C108 and R106 provides another I
