In
load condition the circuit is able to regulate the output voltages within the required tolerance.
The input power is also measured. While delivering the standby load (5 V at 50 mA, 1.8 V,
3.3 V and 12 V at 0 mA), the input power consumption is lower than 800 mW at both
nominal input voltage ranges.
Table 6.
In
there is just a small increase of the input power when the circuit is working close to the
maximum input voltage.
