STEVAL-ISA174V1

7W dual output offline flyback converter for home appliances using VIPer0P. The key feature of this offline converter is zero-power mode (ZPM). It is an idle state during which the device is totally shut down and the residual consumption from the mains at 230VAC is kept below 10mW. The IC enters ZPM by pulling the OFF pin to SGND for more than 10ms and exits ZPM (resuming normal switching) by pulling the ON pin to SGND for more than 20µs. This function can be tested by acting on the tactile switches connected to the ON and OFF pins.
