I need to operate external actuator with DRV2667 Evaluation Module which requires 150 or 200 Vpp, but the output voltage is only 40 Vpp.

How can I increase the output voltage? Is it needs any extra components?

Hi,

here is the user guide of the EVM.

there is some information talking about changing the boost voltage.

we don't need external component to do that.

I read the manual of drv2667evm-ct , but I don't know how to change the values of R1 and R2 to set the boost voltage how can I connect thesethese resistances?

Hi,

please refer to the P26 of the EVM user guide, which has the schematics of the EVM.

it uses the GPIO mux to control the resistance.
