Hi,

Does TI voltage to duty cycle modulator as LTC6992MPS6-1#TRMPBF?

I only can find VFC32, but it voltage to frequency not duty.

Thanks!

Hi Jeff,

I assumed that you are looking for voltage to PWM modulator. As you pointed out, VFC32 is Voltage-to-Frequency and Frequency-to-Voltage Converter.

Below is an example and application note in discrete circuit. If you provided us some design requirements, I can direct your inquiry to a proper supporting team. For instance, the following PWM sinewave example is generated via a high speed comparator (TLV3501), which the IC product is not supported by PRAMPS team.
