Part Number: TPS65023B Other Parts Discussed in Thread: TPS65023EVM-205 Hi, I believe there is an error in figure 3 of your app note for pairing the TPS65023B with the iMX7. R22 and R23 are connected to the output of LDO1 to create a reference for the…
Rafl,
I plugged in a brand new TPS65023EVM-205 with all the jumpers installed in the default positions (LDOEN = DCDC1_EN = DCDC2_EN = DCDC3_EN = On), and I measure 20-30uA typically. Occasionally this number goes up to 60uA (micro-Amps), but never 60mA…
Hi Allen,
Are you looking for timing related to DEFLDO or LDO_EN?
DEFLDO should be tied to GND, VCC or a resistor dividor to the output, so timing has no role.
I will check on typical VCC Power ON to LDO_EN timing based on EVM BOM and setup and assuming…
Hi Rick,
I am not sure if we have data on those specific parameters. I am checking with our testing team now on this. One thing you can do is order the EVM and test for your specific application and anything else you might need. If you do test, be sure…
Will you please provide an oscilloscope screen shots of the issue?
Also, does your layout match that of the TPS65023EVM ( http://focus.ti.com/docs/toolsw/folders/print/tps65023evm-205.html )?
