TPA3132D2: Low Output Power and 2 Ohm load

Nicolas Augier
Prodigy 10 points
Part Number: TPA3132D2


Hello,

I have two questions about the TPA3132D2 amplifier.

I will connect a trasformer after a Class-D amplifier.

The transformer is the 108E by Hammond Manufacturing used with the 3.2 Ohm side as the primary and the 600 Ohm side as the secondary. The amplifier output power needed is very low: 75mW in a case and 300mW in another.
 So, I would like to know if the TPA3132D2 will be able to work correctly with a 5V power supply, a load between 2 and 3.5 Ohm and with the output power values I told you before.
 
The other question is about the 2 Ohm minimum load.
Du you know if  2 Ohm is still the minimum load value in all cases: In Stereo mode and in Mono mode (as shown in page 20 of the datasheet) ?
 
Thank you in advance
Nicolas
