Hello everyone. I am testing a 5V-200VDC-DC converter IC. I tested the IC with a bench power supply, and I saw that it is drawing approximately with 5V: 450mA at start-up, then the current decreases exponentially until it stabilizes at aprox 120mA when connected to the Load.
I would like to control when the ON/OFF state of the converter with an arduino, however, I am aware that the arduino digital pins can only source 20mA safely, so it cannot be done directly.
To provide the needed current, I thought maybe I could use a battery, say a 9V battery with a decent amp-hr, a regulator or Linear Dropout Regulator to step down the voltage to 5V, and connect that output to the converter. But again, how could I control the on/off state of the battery using the arduino?
Is this an okay approach? I'm open to suggestions of course, since I'm fairly new at this.
Thanks, any help is appreciated.
