Other Parts Discussed in Thread: TPS65023EVM-205 , TPS65217CEVM , USB2ANY , TPS65217 Hi,
This is K Harshavardhan.
Thank you for your support in selecting the EVM's of PMIC
For the training we have selected two PMIC 's from your list.

Jun,
You want to order TPS65023EVM-205 to test on EVM.
TPS65020 and TPS65023 are not quite pin-2-pin compatible devices, but they are very close. The only differences between TPS65020 and TPS65023 are: the default output voltages when DEFDCDC1…
Hi Kristin, You are absolutely correct, R22 and R23 for VREF should be connected to DCDC3, not LDO1. We will update that ASAP. We didn't test the circuit with an actual i.MX7 part, but the design was developed in conjunction with customers who were and…
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…
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…
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 )?
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…
