The VSYS pin is at ~3.6V when the battery is installed.
If the system is being powered by USB or AC input, both of which are 5V, is the VSYS pin = 5V or 3.6V? does it depend upon whether a battery is installed as to whether it is 3.6V or 5V ?
Other Parts Discussed in Thread: TPS65073 Hi,
somehow I cannot find anymore the PSP internal community list anymore. If someone could point me to it, that would be great. In the meanwhile I thought I post here.
Could someone comment on how the TPS65073…

Other Parts Discussed in Thread: TPS65073 Hi,
I need the DCDC1 of TPS65073 at 3.3V at startup (default: 1.8V). If I use an external resistor divider (e.g. 1k5:1k8), the 1k8 resistor is in parallel to the internal resistor divider (which I can not disable…

The OMAP clock seems to have impossible requirements.
The TPS65073 design guide says that the OMAP processor requires a square clock
with rise/fall times <= 2.5ns.
The oscillator that…
