TPS65235: Questions about the LNB Out Voltage control VSET[3:0]
Tool/software:
Hi, TI Engineer.
I have a question about the interface of TI LNB IC.
We use I2C and Enable and VCTRL pins are connected to SoC GPIO pins. At this VCTRL pin = "low".
In this setting, the LNB Out voltage is it operates as 14.6V -> 0 -> 14V (I2C setting value). Is this enable and VCTRL setting okay?
Hi Colin,
In the set where the LNB IC is applied, it is operating from +14.6V -> 0V -> +14V or +18V. If this situation is repeated, can it damage the LNB IC?
At this time, the Enable pin is maintained high.
Thanks,
