Hi Anatoly,
The 2phase reference design is available on datasheet.
The attached spreadsheet can be used to select compensation value.

Hi William,
We only have loop calculation spreadsheet for TPS40422.
For 2phase configuration, the LOUT and COUT is inductor value and Cout per phase.

There are several 2phase reference design can be referred…
1/10 of the switching frequency is a good choice.
The bandwidth corresponds to how fast the loop response is, so higher bandwidth means the output voltage can recover much more quickly during load transient.
Here is a design tool/checklist to help…
Hello,
Question 1:
The PMBus command IOUT_CAL_GAIN must be equal to inductor DCR value to make current readout and OCP accurate.
In your case, set IOUT_CAL_GAIN=3mohm
Qustion2 :
Please use attached file for compensation vlaue.
For 2phase…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
