Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: TPS54426 Other Parts Discussed in Thread: TINA-TI Team,
I have seen we have webench and Tina-TI/Psice support for TPS54426.
Apart from the datasheet do we have additional documents (App Note, EXCEL file) to help with system design (like selection…
Part Number: TPS54426 Hi Sir,
The testbench has been configured for VIN = 12V, Vout = 1.05v, IOUT = 4A
Although it is V (VO) after simulation, it does not seem to reach 1.05v.
Is it a normal analysis result?
I tried many things, but V (VO) seems to have…
Part Number: TPS54426 Hi team,
See Figure 14 on page 12 of the datasheet. There is a feed-forward capacitor: C4. 22PF is going to be implemented, but which side is more effective, the VOUT side or the VFB side?
Regards,
Naotomo Nakada
Part Number: TPS54426 Hello,
We have five of these parts in a design and each generate a different voltage. The output voltages are +5.0, +3.3, +2.5, and 1.8 and 1.1V. Each of the converters operated from the same +12 volt input and all have the enable…
Part Number: TPS54426 Hi Team,
A Japanese customer has an issue on the TPS54426 Unencrypted PSpice Transient Model simulation. He downloaded ' TPS54426 unencrypted PSS transient model package (Rev. A)' from TI HP, and imported it to PSPICE.
He got…
Part Number: TPS54426 Hi team,
Could you tell me an input leakage of EN pin, it seen that there is no description in the datasheet.

Part Number: TPS54426 Hi Team,
My customer want to know if they need to take care DC biasing effect for Recommended Component Values indicated in Table1.
Is those value shows nominal value? or effective value? If it means nominal value, they need to choose…
Part Number: TPS54426 Hi team,
One quick question, could you tell me about the connection and correct sense points of Vo and Vfb. According to the datasheet, it requests kelvin connection for both pins and I believe that Vfb should be sensed as close to…
Part Number: TPS54426 Hi,
I was working with the spice model for a TPS54426, and ran into a weird issue. An example would be to set the divider for 3.3V out which in Table 1 of the datasheet shows R1 as 73.2K, and R2 as 22.1K. When I run the simulation…
Part Number: TPS54426 soft start capacitor is 3300pf in reference design, the start time is too long for us, i modified it to be 330pf. i want to know how about the suggest range of soft start capacitor? is there any harm if the capacitor is too big…
