Hello,
I recently put together a stereo amp based around the TPA3110D2 IC. I essentially used the suggested application schematic right out of the spec sheet (fig. 37) with a few embellishments from the EVM schematic (gain control jumpers, plimit defeat jumper, ferrite beads on the supply, just some stuff to play around with.) I used my mp3 player as the audio source. The power supply is a 14.4V NiMH battery pack. The unit works, but only at a low level volume. If the volume on the mp3 player source is turned up above a third of its capacity, the TPA3110D2 amp keeps auto-resetting itself. It should be noted that the only speakers I had handy were a pair of 4 Ohm, 100W rated power speakers. Is the amp resetting due to over current as a result of my speakers? If so, what do I need to do differently? If not so, what's going on here?
Thanks!
Chad
