During manufacture, we have found that there is still a little possibility to encounter such problem.
So we think that this problem may have relevance to soldering.
Are there some instructions…
Part Number: UCD9222 Other Parts Discussed in Thread: UCD7242 , TEST , USB-TO-GPIO
HI,
I have a board with two DSP(C6678). Each one has dedicate one UCD9222 and one UCD7242 to provide Core(rail #1: 1.1V) voltage and fix(rail #2: 1.0V) voltage.
When I enable…
Part Number: UCD7242 Other Parts Discussed in Thread: TMS320C6678 , , UCD9244 , TEST I use UCD9244 + UCD7242 to power TMS320C6678 CVDD.
There are two board, one is work fine.
Another one will encounter FLT condition when the current increase to about 4A…
Your description sounds as though you have the correct method for grounding the AGND to PGND on the UCD7242.
If you'd like I could look at the schematic/layout, we could connect through friend request rather than posting it to the forum.
Part Number: UCD7242 Other Parts Discussed in Thread: UCD9222 Hi:
We use the UCD7242+UCD9222 in my board. it works well in the normal temperature. when the temperature below -10℃,
some boards can power up,but,another can no power up. The case…
Part Number: UCD9222 Other Parts Discussed in Thread: UCD7242 Hello.
I use power control IC(UCD9222 and UCD7242).
For new projects, circuits such as C6657 EVM will be used.
Unlike the EVM circuit, the UCD 7242 input voltage would be 5V instead of 12V…
Other Parts Discussed in Thread: UCD9222 , UCD7242 hi TI professors,
The ucd9222 and ucd7242 to generate core power of C6678. I use Fusion tools download the firmware to UCD9222. But when I power off and next power on，it appears ripple before control pin…
Part Number: UCD9222 Other Parts Discussed in Thread: UCD7242 Hi:
For the 6657EVM, change the power from 12V to 5v, can ucd9222+ucd7242 work ? From the datasheet of ucd7242 , we know the input voltage range is 4.75 to 18V. If it can work, what should…
I think the inductor or capacitor value in your design are different from EVM or has changed. Otherwise the same compensator configuration should work.
It is expected to see loop stability change with switching frequency. With the same parameters in…
Part Number: UCD9222 Other Parts Discussed in Thread: UCD7242 , TMS320C6678 Dear engineer of TI, I am in the process of debugging the UCD9222 and UCD7242 power module. I used the Fusion Digital Power Designer v1.8.230 and use the Firmware Download Tool…
