ULC1001-DRV290XEVM: Frequency range

Anthony De Winne

Part Number: ULC1001-DRV290XEVM
Other Parts Discussed in Thread: ULC1001, DRV2901

Dear TI support,

Q1) What is the output frequency range of the ULC1001-DRV290XEVM ?

Reason for asking is that I'm currently see on the PCB indicating an ouput range of 40-400kHz, while some design papers indicate the frequency range starts from 100kHz.

Q2) The resonance frequency of my lens dome is 6kHz, could that been triggered by the ULC1001 please?

Best Regards, A

Hello,

The ULC system with ULC1001 and DRV2901 has an upper frequency limit of 400kHz due to the driver and a lower frequency limit of around 40kHz due to ULC1001. We are working on implementing a new feature that will change the lower limit to around 10kHz, but 6kHz will still be out of range for ULC1001.
