Part Number: TPS54821 Dear all
I am power system designer for Satellite.
I want to use the TPS54821 for the space.
So I did the TID(Total Ionizing Dose) radiation test.
When over the 12krad, I was failed.
And UVLO voltage was changed from 4V…
Part Number: TPS54821 Hi Sir,
Our customer have PWRGD turn low issue, we are check the schematic PWRGD pull high R is used the 10k,
If we are change to EVM suggest 100k, then Solve this problem.
what change the PWRGD pull high R improve this issue…
Part Number: TPS54821 Hello I'm using TPS54821 regulator in my project. I have used TI WEB BENCH Simulator and implemented my design, wherein it is showing very less ripple value. But practically I'm getting 100mV. I need ripple to be less than 50mV.…
