FSDM07652RB
Typical application circuit
Application
LCD Monitor
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
• 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.
