To whom may concern
Good Afternoon
I have been testing the DC-DC Converter lately and I have noticed the following issue.
When a the turn-on of my power supply, which is connected to Vin, is connected with no current limiter the IC doesn't perform the conversion. However, as soon as i limit the current input before the turn-on the IC operates normally.
This is only taking place on turn-on. after turn on , when the converter is stable, the current limiter of my power supply can be removed.
I cannot understand the reason, why the IC doesn't operate properly when the available current at the input is higher than 1A, during switch on, however if the IC is switched on while the power supply has a supply current of less than 1A then the IC operate normally and the current limiter maybe increased with no issues.
please find the schematic attached below.
the input range is between 6V-115V
Thank you
