HI Sirs,

My cutomer using LP87332ARHDRQ1 and LP87322ERHDRQ1 to support J6Entry,

They found out that BUCK0 vout is 1.32V (should be 1.15V), BUCK1 vout is 1.24V(should be 1.05V) for LP87332ARHDRQ1,

and BUCK0 vout is 1.95V (should be 1.8V), BUCK1 vout is 1.44V(should be 1.35V) for LP87322ERHDRQ1,

Is there any posible for this situation?

now, I want to read the OTP version and BUCK0_VSET from register, but I can't found the GUI from website, and which tool can I using to connect PC and LP8733?

Hello,

There are numerous versions of the LP8733 and LP8732 with different default voltages and startup sequences etc. Since most of them are not RTM'd it would be good to keep the discussion off line. Please send me email directly.

You can find EVM user guide www.ti.com/.../LP87333Q1EVM

Thanks.

Best regards,
