Part Number: TPS62808 Other Parts Discussed in Thread: TINA-TI Tool/software: WEBENCH® Design Tools Hello there!
I optimized a buck converter design over the TPS62808, on WEBENCH Power Designer, only to notice that design can not be exported to TINA-TI…
Part Number: TPS62843 Other Parts Discussed in Thread: TPS62808 , TPSM828301 , TPS62743 Dear Madam or Sir,
is it possible to change the output voltage of the TPS628438 or TPS62808 after the configuration of our FPGA (~200ms + housekeeping) is done.
If I understood…
Hi CSC,
We don't have any device (< 7V VIN ) that has programmable current limits that meets the customers requirements. Usually customers add external current limiting ICs depending on their requirement.
The new dual rail converter, TPS62441 suggested…
Hi Joshua,
In that case, I would recommend using a BQ25155 + TPS62808 which can support 3.3V with a small solution size.
This would be similar to the PMP21884 https://www.ti.com/tool/PMP21884

Hi Shriram,
It looks like we don't have a device that can support a 100us output voltage rise time. The fastest rise time that our device (TPS62808) can achieve is 210us but it is limited to 600mA. Please see attached datasheet for reference.

Hi Raza,
I can recommend some buck converters for your application. The total load for the 2.5V and -2.5V rails is still not clear to me. Nevertheless, please find below some suggestions for our small size high efficiency buck converters: TPS62840, TPS6282x…
Part Number: TPS62802 Other Parts Discussed in Thread: TPS62808 Tool/software: WEBENCH® Design Tools Hi,
I am trying to simulate this device with an output voltage of 2.8V. However it seems that Webench only allows an output voltage of up to 2.2V. I tried…
Hello Serhii,
We don't have efficiency data or bode plot measurement on TPS62205. Maybe you would like to consider newer device which will be more price competitive. TPS62240 (2.25MHz fixed-frequency) or TPS62808 (DCS controlled) can support your requirement…
Hi Derek,
Thanks for your question.
Several of our devices (including TPS62026 ) have the so called 100% duty cycle mode.
In short (you can find more details in the datasheet), when VIN drops near VOUT level, our devices keep the high side Mosfet constantly…
