Part Number: TPS53126 Other Parts Discussed in Thread: TEST2 Hi,
I'm trying to select feedback resistors values for 0.85V and various other output voltages.
In datasheet section 9.2.2.6 Choose Output Voltage Set Point Resistors there is Equation…
Part Number: TPS53126 Hello,
I am trying to make a dual buck design for a project, but I am unable to get an output voltage from either of the two outputs. After reflowing the design, verifying solder joints on the TPS53126, the two SiZF920DT 's and…
Part Number: TPS53126 Dear Sir or Madam,
due to powersupply issues I am trying to make a bodeplot of a powersupply circuit using the TPS53126 IC.
Out of the TI-paper ' D-CAP2TM Frequency Response Model based on frequency domain analysis of Fixed On…
Other Parts Discussed in Thread: TPS53126 Hello,
I was evaluating TPS53126/7/9. The TI website shows Imax of 15A but the datasheet shows max 4A. I was told my a TI engineer earlier that if NexFET's are used with these devices, Imax and efficiency are…
Hello Bruno,
First, you'll need to decide at which switching frequency you want to run the TPS53126? The TPS53126 allows the user to select 350kHz or 700kHz. 350kHz will offer higher efficiency, but will require larger inductors and ouptut capacitors…

Hi Fred,
Your calculation is right, the cap will add a zero, and a pole at much higher frequencies.
The frequency of the zero can be derived from (Rtop * C) , and the frequency of the Pole is driven from ((Rtop || Rbottom) * C)
If you want to understand…
Part Number: TPS54325 Hi,
Recently, I have read an application report, named "D-CAP2TM Frequency Response Model based on frequency domain analysis of Fixed On-Time with Bottom Detection having Ripple Injection"(SLVA546). In this report, it writes "The…
