APPLICATION NOTE
As it is well known, according to power saving
regulations, we need to obtain a very low power
consumption during standby condition for all equipment
continuously powered on the mains. For “not saving”
version of power supply, the standby power consumption is
around 9.0 W (for 100 W power output). When using the
MC44608 GreenLine™ Power supply controller, we obtain
1.3 W in standby mode. The result is absolutely
phenomenal, but still, for some special applications, the
power reduction is not enough. In this case the only
possibility to obtain a lower consumption in standby is to use
a separate low output power supply (< 1.0 W) for powering
only the microprocessor and switch off the rest of the
application. The MC44608 is basically not designed for that
use. However this is achievable by adding a few more
components to the typical application schematic. In this case
we can reach a standby power consumption as low as
200 mW.
