120 W isolated flyback power supply for appliances using LinkSwitch-HP (LNK6779E)

Primary-side regulated isolated flyback converter with ±5% regulation

132 kHz switching frequency for small transformer and output filter size
Full load Continuous Conduction Mode (CCM) operation for improved efficiency andreduced output capacitor ripple current
<70 mW no-load input power at 230 VAC
Multimode operation maximizes efficiency across load range
Extensive protection including OVP, OTP, brown-in/out, line overvoltage, and lostregulation (auto-restart)
88% full load efficiency @ 115 VAC and 90% full load efficiency @ 230 VAC
Easily meets DoE 6 efficiency requirements of 88% average efficiency (end of cable)
Class B Conducted EMI with > 6 db margin
