Part Number: TPS53355 Other Parts Discussed in Thread: TPS546E25 Hello,
We are now trying to replace out power solution from LTM4671 to TPS53355. One problem is as belows:
We hope the voltage decreasing is below 15mv when the load(50%) is coming.
As a result…
Hello,
I believe you are referring to RCC Ripple Injection Circuit portion of the schematic and of the Excel design calculator. You should be able to input your C_Ramp, C_couple, and R_ripple values into the design calculator and it will display the results…
Part Number: TPS53355 Hi,
My TPS53355 would not start up and I checked VREG, it's at 0 V. The input is 12V, output is 1V. Following is my schematic:
Please help me!

Hello Jimmy,
The part number in the thread is TPS53355 but the SCH has a different part number, can you please confirm the right part number
Yuchang Zhang can review the TPS566335
Thanks

Part Number: TPS53355 Hi,
1) How many seconds above the current limit set by the 21pin does overcurrent protection start to work?
2) What is the unit for each parameter in equation (2) on datasheet P18?
Best Regards,

Part Number: TPS53355 Other Parts Discussed in Thread: TPS548D22 Dear Team,
Looking forward to your answer of my questions.
And we have run some simulation on TI’s WEBENCH and found some of them not able to reach 90% efficiency. Since it is evaluating…
Hey Xinjie,
The VREG may jitter due to fluctuations on the input voltage to the LDO. When a load step happens, the voltage at the input can drop momentarily, causing a drop on the VREG input voltage, this is why decoupling capacitor placement and values…
