Dear all,
I wouid like to figure out the instantaneous supply current to TPA3110D2-Q1.
Could you teach me?
I use this device under following condition.
Vcc = 10.6V, Speaker resistance = 3.5Ω.
Under this condition, the instantaneous value was 1.5A of speaker output.
So I think that the instantaneous supply current is 1.5A + consumption current of IC's own.
Is this correct? Should I consider that with efficiency?
And, I think that the consumption current of IC's own is from the resistance of internal transistor and the gate current.
Should I consider these consumption current to the supply current?
Best regards,
