Other Parts Discussed in Thread: UCD90240 , UCD90160 , PTH08T250W Hello,
We consider to use UCD90160 and UCD90240 devices as power supply controller, particularly sequencing and adjusting voltages power rails (with PTH08T250WAD power module) . The devices…
Other Parts Discussed in Thread: UCD90120A , UCD90240 I'm looking at using a pair of UCD90240s to replace 4 UCD90120A parts on a board. The UCD90120A had an undocumented limitation on the current measurement that reduced the 12 bit resolution measured to…
Part Number: UCD90320 Other Parts Discussed in Thread: UCD90240 , UCD90160 , UCD90160A Dear team,
We are using UCD90320 and enable voltage margining function.
Based on margining spreadsheet, F_PWM_Calc is 3.06MHz. But in UCD90xx GUI, we only can set 1MHz…
