Does it have IC can control voltage output by PWM(frequency or duty cycle) or programming with higher effericency?

Hi all, Since I have a new project that need to control the voltage output from 15-30V, and it need to run the motor with loading, so the high current consumption is needed

The voltage output controller is MCU, so it can only be PWM frequency or duty cycle or coding, does it have any DCDC converter IC  can fulfill this requirement with very high efficiency ? 

Thanks all

    Hello Simon,

    Our DCDC portfolio is separate from our motor driver portfolio. I support motor drivers, so I may be able to help.

    If you are driving currents larger than 10 A, you may be interested in one of the devices from our gate driver portfolio. The DRV8701, DRV8702-Q1, DRV8703-Q1, or the DRV8704 may be interesting to you. You will also need to choose MOSFETs to go with these devices.

    Hi James,

    Thanks for your answer, actually, our project purpose is use output voltage higher and lower to move faster and slower the motor, so we prefer use a DCDC converter to achieve the project, is that any possible idea IC for help? thanks for your help!

    Regard.

    Hi Simon,

    I apologize for the delay.

    Let me assign this post to the DCDC converter forum, and they can help you.

    Simon,

    Yes this is possible. You'd essentially take your PWM control signal from the microcontroller and use an RC low-pass filter into the feedback node. Or into an op amp into the feedback node. Or you can use something like this: TPL0401A-10

    If you need more guidance please share more specifics on your specs and I'll recommend something more specific.
