Thanks. I replaced that but it functions on battery and Bluetooth perfectly (with an issue) and when I connect USB cable to pc, the pc makes USB plugged in and then unplugged sound repeatedly.
The issue that I mentioned is, usually ds4 on plugging the battery, there is a startup cycle. It draws approx 40 to 50mA for about 2 seconds and then comes down to 0.1mA. This one is taking 80mA and then rests at 30mA (that's a 30mA leakage and hard to detect even via thermal can). I'm suspecting the mt3610n chip maybe faulty. I did try reflowing.
My question is are the jdm-050 and -055 mt3610s interchangeable?
