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 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 function…
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. > Question…
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 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 5.3V,…
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 to…
Part Number: TPS54521 Tool/software: WEBENCH® Design Tools Hi team,
I have query related to Phase margin calculation and I am using Switcher Pro tool and tsp54521 buck converter.
According to the tps54521 datasheet i have calculated poles and zeros frequency…
Part Number: TPS54521 Other Parts Discussed in Thread: TPS54302 Hi there,
We used the TPS54521 for main power supply unit in mobile camera apllication,
Now we faced to solve the EMC(conducted emission) issue for automotive application using TPS54521, b…
