A question about power inverter chips? Answered

I need an inverter to use the 12DC of a battery to get an AC varying from 1 to 12V, and also the frequency has to be varying from 10 to 80KHz. the inverter will need to deliver 2W max. 

I want to know if inverters do even exist in of IC chips, or will it be a board that i can buy, or am i obliged to make it myself?
does a 2W inverter even exist or do people use oscillators for these kind of powers?

A signal generator plus audio amp should do the trick in terms of power and frequency range.
You might have to adjust the output to be a good AC that is equal above and below the zero volt line.

+1. Although I'm not sure if a typical audio amplifier has much gain above 20 KHz or so, since that's the approximate upper frequency limit for human hearing. Not sure. Should probably check the amp with a dog or cat, or an oscilloscope. ;-)

It won't be as simple as a single IC. It will be hard to find an available schematic or pre built product for this. This will be a very complicated build even for someone with an electronics engineering background.

What are you building this for?

i do have electronic engineering background (but more in controls), but no knowledge on premade chips on the market. i want to use it for a power supply for a wireless energy trasmitter which is controlled in frequency to follow a resonant frequency that changes when the charging receiver is moved. i want to control it so that it keeps the same power and voltage on the other side.<
it doesn't have to be one single ship, i can connect many modules
