Part Number: TPS54231 Tool/software: Hi Team
Customer is using this device to convert 12V to -12V. the following is the output of device. customer found there is slope of output as start-up. the slope will be worse with the load increase.
Can you…
Part Number: TPS54231 Tool/software: Hi ,I am design a buck converter for 3.4 V (100mA).At no load condition i am observing 50 mV ripple.But in 80 mA load , I am observing 1.8 V ripple and efective DC voltage is 3.8 V in that Case.I am aatching my design…
Part Number: TPS54231 Other Parts Discussed in Thread: TINA-TI Tool/software: I am running simulations of this IC on both LTspice and TINA-TI. I have used the same values and circuit as shown in the TI power designer (Webench). The simulations on Webench…
Part Number: TPS54231 Hi,
To avoid any risks of damame IC and inductor during OCP, the saturation current of inductor at least is bigger than max. Iocp (5.3A).
but in tps54321 datasheet, the 3.04A saturation current inductor is chosen. is this an…
Part Number: TPS54231 Tool/software: Hi ,I am design a buck converter for 4.4 V (100mA).At no load condition i am observing 50 mV ripple.But in 80 mA load , I am observing 1.8 V ripple and efective DC voltage is 3.8 V in that Case.I am aatching my design…
Part Number: TPS54231 Tool/software: Dear all,
I have used below circuit for generating the fix +5V when input varies from +16Vdc to +24Vdc. but i am not getting the output voltage of +5V.
When increase the input voltage at same time output voltage…
Part Number: TPS54231 Tool/software: Is there any maximum (or minimum) input / leakage current value regarding VSENSE? It could affect the precision of output voltage, and I would like to calculate with it.
Thank you in advance,
Norbert
Part Number: TPS54231 Tool/software: Hi Dears,
Our customers use TPS54231. The customer purchased two batches, but the chip screen printing was different. Could you please help to check it?thanks
Part Number: TPS54231 Please allow me to confirm the usage of TPS54231. While using the TPS54231 as an inverting power supply, the same peripheral component failure has occurred on multiple boards. The design of the power supply circuit is based on the…
Part Number: TPS54231 Tool/software: Hi, I purchased some power ICs from a trusted, well-known supplier. Over the years, the TPS54231 chips I received had consistent shape, packaging, and performance. However, I recently started noticing performance issues…
