Thanks for your answer.
Unfortunately it doesn't work this way. I can control all registers and set bits but the rails doesn't react. V3P3 works but not the rails.
However at GPIO control all rails work perfectly.
Perhaps I need to read out or write…
In meanwhile I found out, that it's possible to activate both voltages (VCOM + rest) by going from sleep -> active modus directly with GPIO control.
But it isn't possible going from standby mode into active mode (VCOM + rest of voltages) by GPIO control…
Your i2c host may require a pull-up to drive the SCL line, but the PMIC does not.
As far as the PMIC is concerned, SCL is only an input, so it does not require a pull-up to operate. The SDA pin is an open drain output and thus requires a pull-up to…
Thanks for the answer. The TPS65185 should be the better (newer) one than the TPS65180?
But I've got still a quite old display anyway?! (ED097OC1)
What would you recommend: TPS65181B or TPS65185
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…
