Part Number: TPS65131EVM-839 Using the TPS65131EVM-839 board, I find the negative output is unstable with varying load. Using a programmable load, stepping between 10ma and 50ma with 4ms period, I observe the output voltage oscillate. I've attached a…

Part Number: TPS65131EVM-839 Hi Team, We have a customer requesting for the 3D model (STP file) for TPS65131EVM-839. Please let me know if it is possible to request this file for this board. I will send the customer information offline if needed. Thanks! J…
The following are the scenarios I have debugged: 1. Connected +12/-12V to THS3095EVM -> works good, I see an amplified signal without any heating up or extra current consumption 2. Connected +12/-12V to THS3095 on a breadboard with 100nF and 22uF decoupling…
Hi Andrew,
I do not believe board layout to be the cause of this and I think we need to find the root cause before thinking about making a new board. Is it possible for you to get a TPS65131EVM-839 board and blue wire that into your battery and TPS7A39…
Part Number: TPS65131 Hi Team,
R6 and R12 in EVM board(TPS65131EVM-839) do not appear in typical application of datasheet, but no R6 and R12 output voltage is incorrect. For EVM board, the output voltage is ±15V and R6 and R12 are 51.1k. If the…
Hello Hirokazu-san,
There is an EVM available for TPS65131 and you can order it on ti.com as TPS65131EVM-839
VFBP and VFBN are feedback voltage ranges for the boost and inverting buck boost converters respectively and the internal control loop strives…
