Dear all
I tested the relationship between switching frequency and the efficiency of TAS5805M-EVM.
Test condition:TAS5805EVM, Ferrite Bead, PVDD=16V;Load=6ohm;Output power=10W;
I think the efficiency will decrease with the switching frequency, because of
the switching loss. But the efficiency increase with the switching frequency.
Test result:
The test result is:
Fsw=384kHz;IIN=2.222A
Fsw=480kHz;IIN=2.157A
Fsw=576kHz;IIN=2.123A
Fsw=768kHz;IIN=2.073A
Thanks and best regards,
Ella
