Part Number: TPS53355 Other Parts Discussed in Thread: TPS53353 , Hi All,
I have a question about Cin limitation of TPS53353.
Usually we will directly use the Vin ripple to evaluate the Cin requirement.
But as I know, the D-CAP control method…
Hi,
Can you please clarify what is the confusion that you have on the short circuit protection and over-voltage protection.
Can you please share your WEBENCH design? A quick way to review the design is to simulate the design. WEBENCH has simulations…
Part Number: TPS53355 There is a section on page 24 discussion the overcurrent detection threshold.
There is a statement:
Use an RDS(on) value of 1.5 mΩ for an overcurrent level of approximately 30 A. Use an RDS(on) value of 1.7 mΩ for overcurrent…
Part Number: TPS53355 Other Parts Discussed in Thread: TPS53319 , , TPS53353 Hi Team,
Customer wants to use TPS53355 to replace TPS53319 in their board because of device shortage. I check both D/S, these footprints are same. Do you think are there peripheral…
Part Number: TPS543B20 Other Parts Discussed in Thread: TPS53355
I'm choosing a DC-DC converter for a design with Vin = 12V in, Vout = 5V, and Iout = 15A, target for FPGA power rails. The two candidate chips are TPS53355, and TPS543B20. TPS543B20 use…
Part Number: TPS53355 Tool/software: WEBENCH® Design Tools According to the design of WEBENCH, 12V was input and output was 0.9v / 23.4a. The load was CPU, and the output was ringing, Rr=105K and Cr= 6.8nf.How can you eliminate ringing?thank you
Part Number: TPS53355 We have used TPS53355DQPR to design a VR with below spec. Do we need a heat sink or GND thermal pad is good enough to cool. It is 16 layer board where we have GND on TOP (under the IC) and 6 inner layer.
Design Spec
VIN - 12V…
Part Number: TPS53355 Other Parts Discussed in Thread: TPS53353 Hi
My Customer has question.
Customers are considering TPS53353 and TPS53355.
Measurement of the SW waveform with the EVM showed a difference in ringing noise, and Peak increased in…
Part Number: TPS53355 The output voltage will boost to 2.2V when the DUT power off;The VIN and VDD is stable 3.9V ；The voltage of pin EN is 1.2V ;The output voltage will boost when SW act;
Pls see the detail message from attached pic and schematic；…
