Other Parts Discussed in Thread: TPS65023, OMAP-L137
Hi out there,
seems half of German TI is on holidays (and the other half doesn't know a bit about OMAPs) so I'll have annother shot here:
Does anybody know which currents the 'L137 takes on the 1.2V, 1.8V and 3.3V rails?
There must be a reason why Spectrum uses the TPS65023's 1.5A switcher for 1.2V, the 1.2A for 1.8V and the 1A for 3.3V. But for my new board I'd like to know whether I need a separate supply for my own parts or can 'suck' from the TPS65023 too.
Unfortunately I don't have a EVM available at the moment to take measurements.
I've searched the current 'L137 datasheet (rev. B) with key words like 'power', 'current', 'mA' and 'supply' but there seems to be no detailed info.
Any hints?
Stefan
