Hi fellow peers,
I recently purchased an EVAL-ADP 5090 charge pump to be used in my final year project.
Based on the user guide provided, i connected approximately 450 mV to Vin at pin J6 and has a 2300 uF capacitor connected at J5. Upon starting my experiment, i found that i was not getting any voltage output from the capacitor shown on the readings of the voltmeter. Could anyone provide any assistance as to this problem?
Any help in much appreciated, thanks!
A picture of the connection is attached below.
I just want to check if the board is okay or not. Actually ADP5090 can start working with 380mV typical input voltage.
With the capacitor at BAT pin, ADP5091 should be better than ADP5090 as ADP5091 is improved to charge the capacitor. But you can try ADP5090 at first.
