Convert Analog (output from 10W amplifier) into PWM Signal to drive DC Load

Other Parts Discussed in Thread: UCC28C43

Hi All,

Good Day,

For a project i needed to drive a 'DC load' by 'Analog electrical voltage' which is output of a 10W amplifier. For this i required to change Analog electrical voltage output into equal PWM signal. How this can be done? Could anyone guide me?

Maximum operating voltage for the DC load is 3V.

Thanks,

Hi Moorthy,

Do you have a schematic that you can share. May be you can also clarify what you mean by DC load, it is resistive load?

It is possible to use the UCC28C43 type controller open loop and to input a dc voltage as a control signal to the IC and get a variable PWM gate drive from the IC.

Regards

Peter
