Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Karolijn,
Although I think it is unlikely to be the root cause of the problem, one of the photos you sent worried me: it looks like the I2C "blue wires" from the Saleae to the TPS65070EVM-430 board are not connected to the right pins.
On the…
Madhu Wesly said: T he converters stay ON continuously even if during the switching from event 5 to 6
This is the true statement, as long as POWER_ON stays high during the switching event.
In my test setup on the TPS65070EVM-430, I used AC = 5V and BAT…
Other Parts Discussed in Thread: TPS65070EVM-430 , TPS65070 I am using TPS6507x control software V1.0.0.1 with the TPS65070EVM-430 evaluation kit.
I noticed that changing TPS65070 register values does not change anything in the hardware (i.e. toggling regulators…
The datasheet says on page 34:
"10.3.11 Enable
To start up each converter independently, the device has a separate enable pin for each of the DC-DC
converters. In order to enable any converter with its enable pins, the TPS6507x devices need to be…
Madhu,
As my colleague mentioned, the TPS65070 device might reach the 2.1A forward limit of the FET before the output of 2A is reached by the output. The current through the inductor will be higher than the output.
Before considering your follow-up…
Madhu Wesly said: 1. What is the maximum INPUT supply we can give at AC?? Can I power-up the PMIC with 9V(max)??
Realistically, no, the PMIC will not operate as expected if VAC = 9V because the over-voltage protection will prevent 9V from being present…
Hi,
Yes, this should be able to work just as the same. However, this PMIC is typically meant for customer hand held devices that would probably not be LiMn2O4 but, rather a Li-Ion Poly or LiCoO2. With a LiMn2O4 battery I expect you might want more current…
Other Parts Discussed in Thread: TPS65072 , TPS65070EVM-430 I have the same Problem like this old post: http://e2e.ti.com/support/power_management/pmu/f/200/p/139079/519274.aspx#519274
If I switch on the backlight driver all goes well, but if I switch off…
Other Parts Discussed in Thread: TPS65070 , TPS65070EVM-430 Greetings,
Can i use your wLED boost module as a simple DC-DC step-up converter (to have 12V)? What must be done for it?
Best regards,
Vsevolod Anisimov
