    Hi, Pandian,

    Look at something like TPA0312.

    BTW, in order to get 2-4W, you need more than 3.3V. So, your output power is going to be limited by your supply voltage. If that power is required, you will need to use something like 2xTPA2025D1 + TPA6132A2 for a solution. The TPA2025D1 includes an integrated boost which can give you the power you're looking for.
