TPS53667: I would like to know performance data

Part Number: TPS53667
Other Parts Discussed in Thread: TPS53647

Our customer is thinking to use TPS53667 and CSD95490 with the following condition.
Could you measure TPS53667+CSD95490 performance data?

We would like to know Thermal data, efficiency, load transient(25A to 100A, 40A/us).
Output voltage target is ripple is 6mV, transient is 0.6V+/-5%.

Vin: 12V
Vout: 0.6V
Iout: 120A
Fsw: 500kHz
5 phase

  • Hi Kohei,

    I don't think there is a test report available under those specific conditions currently that I can send you unfortunately. Your best bet is to order an EVM or contact a local FAE for support.

    You can get an efficiency estimate from the CSD95490 datasheet by contacting the FET product line and using the loss curves provided. Also, be sure to look at TIDA-01419 which uses the TPS53647 to hit similar specifications to yours. TPS53647 is the same part as the 667 only it supports 4 phases max instead of 6 but performance is the same in regards to transient response.

    Thanks,

  • Carmen-san,

    I cannot TIDA-01419 design on your web. Was it removed?

  • Hi Kohei,

    It looks like the main page got hidden somehow during site changes. I've got the necessary people working on restoring it so you can view it. In the meantime, check out the test report section which can still be seen. Sorry about that.

    Thanks,

    Carmen
