Part Number: UCD74111 Other Parts Discussed in Thread: UCD9222 , Tool/software: Hello,
We use the Fusion digital power designer tool to program 2x core voltage regulators UCD74111 with the UCD9222 regulator. We used version 7.10.1 Under Monitor, where…
Part Number: UCD74111 Other Parts Discussed in Thread: UCD74120 , All,
Please confirm the size resistor that should be used for AVGG. I see it is recommended between 1 and 2 ohms however what wattage value? I found this used on a schematic for the…
Part Number: UCD9222 Other Parts Discussed in Thread: UCD74111 Hi,
Because I am using the UCD74111 and it already has a high speed comparator for the current limiting is there a reason to enable the comparator (associated with CS1A, CS2A) within the…
Other Parts Discussed in Thread: UCD9244 , UCD74111 This is my second design using this part however this time I am getting a single pulse FLT from the UCD74111 during the soft start. The UCD9244 will send roughly 6 to 8 PWM pulses with a 30ns width …
Your issues with regulation are probably more related to layout than configuration although loop response can be a source as well.
Is there any decoupling at the source of your feedback lines by the load?
The feedback lines run quite close to one…
Other Parts Discussed in Thread: UCD74111 , UCD9224 Hi ,
Kindly review the design and configuration file for our 4 phase 1V supply using UCD9224 and UCD74111.
The specs for the design are:
1. 12V to 1V @ 48 A (SoC requires only 40A)
2. 4 phases…

The E version was a FW spin for a large telecom, I do not know why it was never rolled out to general market but it has been offered to other customers previously.
If you need more than 25A then you could always set the UCD9246 to implement two phases…
Hi,
Starting problems on my digital power solved. The problem was not on operation of the power manager UCD9090, but on starting of the power stage UCD74111. I adjusted fault responses on my UCD9222 design to restart up to 5 times and got the prototype…
