Good morning,
we just made a new project that uses MP1477HGTF-Z as input power stages. We used the diagram with the same components shown in the data sheet for the configuration Vin=12Vdc, Vout=5V, Iout=3A.
From the data sheet it can be seen that there is an Iq of 200uA, while what we measure at the input is 11.2mA with the no-load output circuit.
Do you have any suggestions on the reason for this anomalous no-load absorption with respect to what is reported in the documentation.
Regards,
Renato Dal Monte
Hi Renato,
There was a similar forum question that you can refer to that may help.
