Part Number: TPSM846C23 Hi,
The datsheet shows these 2 pins can be floated or connected to AGND or PGND.
However, the layout example in page 78 of the datasheet shows tiny pads (circled in green below) to AGND. Do you recommend connecting these…
Part Number: TPSM846C23 Dear,
I want to set TPSM846C243 default voltage 0.8V.
I don't have the conditions to perform initial setup through PMBUS without Rset
Can it be set up before leaving the factory?
Thanks!
Part Number: TPSM846C23 Plan to connect TPSM846C23 to a PMBus host with 1.8V logic. The other thread indicates the CLK and DATA can take 1.8V logic. Can I put a pull-up to 1.8V on the CNTL pin as well? The datasheet shows CLK, DATA and CNTL have the same…

Part Number: TPSM846C23 Tool/software: Hi,
1) Without PMBus
In my Board , I've designed TPSM846C23 power module to get 0.8V output. In Datasheet mentioned that, it is possible to operate the module without the need for a PMBus interface. To set…
Part Number: TPSM846C23 Tool/software: Dear Team,
In my board I'm using the power IC TPSM846C23MOLR which is configured to provide 0.68 at 70A via a master and slave configuration. The circuit was working fine for the boards. But now for some boards…
Part Number: TPSM846C23 Tool/software: Dear Team,
We had used the power module IC TPSM846C23MOLR in my board. We had followed the stencil design as provided in IC datasheet as mentioned
During the assembly process, after assembling the components…
Part Number: TPSM846C23 Tool/software: Hi,
We are using TPSM846C23MOLR power supply in our design with PMbus commands. We need the output voltage increments within 5mV.
We want to know the step size and resolution of the regulator and can we change…
Part Number: TPSM846C23 Tool/software: Dear Team,
After removing one power module in the stacked configuration. The output of the power module is showing 3.7V instead of 0.68V.
The clocks are coming properly. The DIFFO pin is showing only 0.004V and…
Part Number: TPSM846C23 Tool/software: Dear Team,
In the power module, PIN 38 (VOUT) is showing short with respect to ground (removed from the board and checked the component)
What might the cause for the short and possible remedies to remove the…
