Does CSD95410 has internal phase shifter to stagger PWMs?

Other Parts Discussed in Thread: CSD95430, TPS536C7

Hi TI,

 

I wish to check, when CSD95410 is working with TPS536C7B1, does CSD95410 has internal phase shifters to delay the PWM input from TPS536C7B1 to form several phases? Or all the PWMs should come from TPS536C7B1?

 

Thanks and looking forward to your reply.

 

Best,

SP

    Hi Siping,

    CSD95410 does not have internal phase shifter, multiphase PWM is intended to come from the controller (such as the TPS536C7 you mentioned). If more than 12 power stages are required, we recommend paralleling power stages to have multiple (up to four) power stages per PWM signal. The CSD95430 power stage is designed specially for this application.

    Thanks,

    Travis
