FA5530 Overview
Quasi-Resonant IC FA5530/31/32.
FA5530 Key Features
- Internal start-up circuit with 500V rating and low frequency operation achieves 140mW input at no load
- 3 35V ( 9900μF ) 1000μF 35V 2200pF T1 Bead 4700pF
- Low frequency switching such as 1kHz at light load reduces standby power
- Maximum frequency limits EMI noise and switching Loss
- Switching at Valley of Vds : Turn-ON Loss and Noise are very small
- Low dV/dt of Vds at Turn-OFF by a capacitor connected between Drain and Source of Power MOSFET : Turn-OFF Loss and Noise
- Demo Board Specification Input Range : 80Vac to 264Vac Output Rating
