Part Number: TPS54521 Tool/software: Hi TI Team,
We are planning to incorporate the TPS54521 in our design to convert 12V to a stable 1.8V output at 2.5A. I have attached the schematic and calculation sheet for your reference.
Could you kindly review…
Part Number: TPS54521 Other Parts Discussed in Thread: TPS54620 Do we have Pspice model for TPS54521. If not then is there any close model for this part ?
Part Number: TPS54521 I would like to share with you our design for this DC-DC converter: TPS54521RHLR. We found out that this this chip goes short (output is short to ground) quiet often in the field due to a power cycle or reset. Could you please verify…
Part Number: TPS54521 Dear Team,
out customer would like to understand the VREF spec of the TPS54521 better.
In the data sheet, we have them at 2 places:
The spec in the table on page 4 is MIN/TYP/MAX for the full temp range of -40...125C…
Part Number: TPS54521 I have two question about overcurrent protection for TPS54521, please let me know below.
①Are there maximum value for High side and low side current limit?
Datasheet is described only min and typ value.
②Which is current limit…
Part Number: TPS54521 Hi,
I have designed a circuit using the TPS54521, Vin=5v to 12v, Vout=5.1v. I understand that if Vin drops below 5.1v, Vout should track Vin because ic having 100% duty cycle.
But in my circuit if input voltage drops below 5…
Part Number: TPS54521 Hi there
we use 4~8 pcs of TPS54521 and other synchronized DC/DC， each powered 5V/5A. As required by system design, all DC/DC will be synchronized with external clock generated from FPGA.
Our questions is, can we use ONE clock…
Part Number: TPS54521 Hello, I have an application that needs Vin=12V-16.8V, Vout=12V, Iout=4.5A.
Of course it is not possible to have 12Vout when Vin approaches 12V, unless the part supports 100% duty cycle.
However, it is not essential in our application…
Part Number: TPS54521 Dear all,
In our customer's design, a reverse current flows for input from the output. I attach this design's circuit and a waveform.
Does this phenomenon not damage a device? How much can you permit the reverse current when…
Part Number: TPS54521 Hello We have been using the TPS54521 for approx 5 years without problems. - (approx 40K pieces) On one design we are see a very high rate on failure in that the device fails and the output goes S/C - approx 1.6ohm This design is…
