Hi everyone .
there is UCD9222+UCD7242 in my project about 6678.When I configure the UCD9222 through PMBus adapter,the UCD7242's output is zero.I find out that the DPWM1A and DPWM2A is 1.65V,so the UCD7242 shut the HS and LS.Does somebody know why the DPWMA is 1.65?my configure file is the project file which is used in 6678evm,and I have pulled up ENA1 and ENA2,also the CTL.thanks.
We have also programmed UCD (9244) over PMBus by C6678. Each configuration command (byte, word, block) was validated by reading it back. But there is no PWM pulses from UCD9244, DPWM output is 1.65 V too (3-stated and pulled to 1.65 V by UCD7242 internal resistors). guoping Lee or anybody, did you solve this problem? TI's representatives are so quite...
Hi Vladimir Podgoretskiy
We did not solve the problem.Do you know how to solve it?thanks
HI,I have met the similar problem as you ,have you solved the problem yet? Could you give me a reply? Thanks
