Part Number: TPS65217DEVM Other Parts Discussed in Thread: TPS65217 Tool/software: WEBENCH® Design Tools Hello
TPS65217DRSLR IC have a power on issue when its connected to DC power source through toggle switch sometimes, but IC continuously Operate…
Part Number: TPS65217DEVM Transient loading of LDO1
Transient loading of LDO_3 looks as expected but the transient load of LDO_1 looks more like a Buck than a LDO,( See screen dumps) could you explain why ?
Hi Kuramochi-san,
The Global State Diagram (Figure 20) in the TPS65217x datasheet shows how the device will operate when PWR_EN is pulled low, and Note (4) shows that SYS will be connected to BATT in the OFF state, even if you are operating without…
Can you provide I2C log file (.txt or .CSV) for the working LDO transactions and the failing DCDC transactions?
Preferably, the data log will be captured by an external I2C sniffer (Saleae, TotalPhase, Tektronix) attached to the SDA & SCL lines.
No problem. You're quite welcome and we are happy to help.
If there are any issues with your custom board, please start a new thread to ask these questions and attach your schematic as a PDF if possible.
Part Number: TPS65217DEVM Other Parts Discussed in Thread: TPS65217CEVM Is the TPS65217D compatible with DDR3 memory if used in a circuit designed for TPS65217CEVM?
Hi Ertugrul,
Is the battery connected to anything else in the circuit besides the PMIC?
OFF state input current should typically be 6 uA at room temperature according to the datasheet:
I just checked this on our TPS65217DEVM and I confirmed the…
