Robustness: 800 V avalanche-rugged power section plus embedded failure protection
functions
Cost saving: Easy design for positive and negative voltages with minimized total
component count
Flexibility: Same PCB for PSU from 1 W to 12 W
Energy saving: 30 mW PSU standby and high efficiency
Energy saving: 30 mW PSU standby and high efficiency
Cost saving: Minimized design for positive or negative voltage without transformer and
self supplied.
In case of fly-back converter, eliminates the auxiliary winding.
EMI: Easily meets the EN550022 class B specification
