The output Voltage expected is 6V and output is constant for 110VAC input. But the output is turning ON/OFF for 220V input. Please let me know to resolve this issue. I have followed the ST Design suite for the design.
could you please provide the complete specifications?
You speak about a 6V output voltage, but in the schematic the expected value is 5V, and even the output divider is sized for this last value.
Complete Spec is Non Isolated Buck Topology with Universal mains 85-265VAC, Expected Output is 5V with 5% voltage regulation.
I have increased to 6V Since there is drop of around 1V from No load to full load voltage.
As I said the Output @ 110V was steady but @ 220V, voltage was fluctuating as shown in picture.
we need even the output current, please.
