Part Number: TPS54719 Other Parts Discussed in Thread: TPS62870-Q1 , TPSM8287A12 , TPS568215 Hi,
We are planning to use TI buck converter part no. TPS54719RTER as 3.3V Output powering VCCIO of two Xilinx FPGAs Spartan-7 (XC7S50-1FGGA484C, 2 qty)
VIN…
Hello Lanxi,
We have high current device with lower Vout ( https://www.ti.com/lit/ds/symlink/tps62870-q1.pdf ).
For which application, you need this minimum voltage?
Thanks,
Farheen
Hi Sam,
Thanks for the clarification. TPS6287x-Q1 offers better efficiency at 3A and above load. By the way, only TPS62870-Q1 have the 0.5V default output voltage version while TPS62874/5/6/7-Q1 doesn't have it.
To address your previous queries…
Part Number: TPSM82866A Other Parts Discussed in Thread: TPSM82823 , , TPS62870-Q1 Hi Expert,
My customer have question about TPSM82866A and TPSM82823. They used TPSM82866A and TPSM82823 in new project. But output current design change, they have to…
Part Number: TPS62813-Q1 Other Parts Discussed in Thread: LM63635-Q1 , TPS62870-Q1 Hello,
We are having a requirement as below:
Buck Converter 1 -
Input Voltage: 4V to 5.5V
Output Voltage: 3.8V
Output Current: 3A-3.5A
Buck Converter 2…
Hi Chris,
I assume Vfb in the (1) formula is fixed at 0.6V, is it correct ?
If my load is purely resistive, won't my control voltage I apply with the DAC also depend on the load's current value ?
I wish TPS62869 and TPS62870-Q1 were available but…
Hi Shifali,
Our TPS62870-Q1 should be on the web in the next few days. It can operate from 3.3Vin. You can parallel 2 or 3 of them to get your 30-35 A.

Hi Shubiao,
Thanks for your question.
As specified in the datasheet, "The output voltage can be stepped down to as low as the 0.799-V reference". You can just connect Vsense to Vout.
Please pay attention that this device is a last time buy. The…
Part Number: TPS62A04AB Other Parts Discussed in Thread: TPS62810-Q1 , TPS628304 , TPS62868 , TPS62865 , TPS62870 , TPS546E25 , TPS628303 Hello, I am doing costdown for FPGA power rail. Is this TPS62A04AB good for this purpose (only 0.1 dollar/1ku)? The…
