I have a question about the quiescent current of ADP5304.
The output is set to 1.8 volts and the input is 3.6 volts.
For the sake of meeting the spec about 180 nA with occasional switching, there were some common mistakes that I try to avoid.
1. There is no probe connected with input & output node
2. Use DMM ( 34465A ) 's smooth filter function
However the lowest quiescent current from my measure result is about 280 nA. ( The attachment shows my average result )
Is there something I should do to meet the spec ?
Thanks for sharing the information.
The typical quiescent current is 260nA rather 180nA. You can check the ADP5304 datasheet.
Thank you for sharing the information and hard work.
But the Figure.13 shows the measure result is 180 nA from ADP5304 datasheet.
Which measure result I can follow ? ( 260 nA or 180 nA )
Please use 260nA as this spec. the figure should be wrong. Sorry for the confusion.
Thank you for clarifying this question.
Could you provide the correct information for ADP5304-IQ at different VIN?
Than how about the efficiency of ADP5304 ( Fig.5 ) ?
It seems very similar to ADP5301’s results.
The Iq with VIN is as below. The efficiency would be only impacted a little under 1uA load current. Not sure what range of load current you care about.
