Part Number: TPS61310
I have a TPS61310 and trying to use LED2 in "video light" mode and output a current of 325 mA. The datasheet shows it is supported by setting the Tx-Mask GPIO to 1. I have attempted this many times and have verified the Tx-Mask Input is being set high.
The order of operations I am performing are:
1. set DCLC2[2:0] to 111
2. Set Tx-Mask high
3. Set Mode control to video light mode
The current being output is only 175 mA.
One other thing, the TI TPS61310 EVM GUI only shows the possible current values up to 175 mA, does this function actually work on this device?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Harini Sankabattula:
1) Are you testing this on your system (or) on TI EVM? on system
2) To set Tx-Mask high, what voltage are you pulling it to? Wondering if it is really high. Tx-Mask pin is 3.3V , I'm sure it's high.
Please refer to the schematic below.
ok,if have new update information,Please let us know,
