TPSM82821: DCDC release date

Yossy Goldenberg

Part Number: TPSM82821

Hi,

I intend to use TPSM82821 in my new design, and I have some questions regarding the product:
1- The product status is ‘preview’, is there any release date?
2- Will it be Ok to use this product to power FPGA (1.2V and 3.3V)?
3- I need to power a transceiver which consume about 0.8A, via a transformer, in transmit mode, and around 50mA when going into receive mode and vise versa. The transceiver uses a 47uF capacitor. Can I use this product with those requirement?

Since my product is very small (about 3cmm X 3cm), I need the smallest DC/DC with minimum additional components, is there any other DC/DC that can be used with those requirements?

Generally I am using LMZ10501silt for my designs to power FPGAs, but this product seems to requires more capacitors and it's a consume more space. will it be OK to power the above transceiver with LMZ10501silt, if the TPSM82821 release is not set yet?

Thanks!

Hi Yossy,

The TPSM82821 is set to be released mid November this year, so quite soon. It should be good for powering an FPGA.
As per page 21 of the TPSM82821 datasheet the maximum recommended value of the output capacitance is 47uF.

You could also have a look at the TPS82084, which has been released and it's recommended output capacitance is up to 150uF.

Also I don't see why the LMZ10501 couldn't power the load you are describing, check page 16 for the maximum recommended output capacitance.

Regards,
Davor
