UCC21331: Suggestion for 1 channel gate driver for Buck Converter

Part Number: UCC21331
Other Parts Discussed in Thread: UCC21750

Tool/software:

We want to use High Side Gate Driver for our Buck Converter. Currently we are using one channel of the UCC21331, and don' t need the 2nd channel.  Can you suggest 1 channel gate driver that is compatible?

We do need the EN functionality, with the same polarity as the UCC21331.  We want to connect this pin to the /OC output of the TMCS133C5A current sensor.

For the pin voltages: 

 

VDDA is ~ 12Vdc above the VSSA

VSSA is 300Vdc

INA is interfaced to 280049C control card digital output...

    Hi Shruti,

    Based on your enable pin requirement, I would recommend possibly looking into UCC21750. This part features more protection features that could be beneficial for your system. However, if your current implementation already works and is cheaper overall to implement, then it is okay if you utilize only one channel of a dual-channel driver.

    Best regards,

    Will
