ADUM4120 VDD2 POWER SUPPLY

ADUM4120 VDD2 has been tested in 250mA and 1A.

we are evaluating this P/N, for 2A+ current ability, and Switching Frequency 200Khz. Solar PV application.

Could you tell me the power supply for VDD2 of ADUM4120 recommended value? 250mA?

we use 16pcs in one board, so the total power consumption is a problem to us. and also the cost is sensitive.

So could we use {50mA or 100mA with big capacitance discharge} to instead of 250mA power supply?

pls advice. thank you very much.

 

if we use big capacitance, UVLO function may lost in test.
