Other Parts Discussed in Thread: TPS2552
hi ...
I'm using the mentioned launchpad and powering it with micro USB .
when i connected ADREFHI ( i connected this to 5.1 v which is in appropriate range respect to TSM570 data sheet for maximum values) and ADREFLO to the Ground .... when i doing this the Red Over Current LED next to j6 appears and no matter how many times i cycled power still CURRLIM LED state is on and device not working .
I try to using the optional power jack and in this scenario the ERR LED apears .
i skim through the board layout and schematic but find nothing ... i read the TPS2552(current limiter for bus powered purposes) data sheet and under section 9.3.3 it tells me that when the condition which caused the over current deasserted after power cycling the chip the device should go to the normal operation ...
the board is now connected to micro usb and nothing else ...
