Part Number: TPS54427TPS54427 support,
I tried simulating a load transient with TPS54427, and it doesn't allow any change to the load current. It seems to fixed at 10% to 100%.
If you open the settings for the load, you'll see () instead of "I1"…
Hi Takahashi-san,
TPS62135 seems to have the best theta-ja in the above devices. I agree there is some discrepancy in the way this is being reported but I do not have the root/history on TA limitation on the TPS54427. But given the limit in the datasheet…
Part Number: TPS54427 Hi Dear,
I bought a new batch of TPS54427DDAR.But the X ray result is slightly different from what I bought before. Could you please advise if it`s normal?
Thanks!

Part Number: TPS54427 Dear all:
I'm using TPS54427, output 3.6V.When testing the radiation, it was found to exceed the standard. The following is the schematic diagram and PCB Layout. Please help to check, Any Suggestions for reducing radiation?…
Part Number: TPS54427 Hi,
My customer is evaluating TPS54427 for a 12Vin 1.2Vout 4A design. basically refer to WEBENCH, but a slight difference of the BOM. so far, they are also evaluating another device , need to confirm this design ASAP. please help…
Part Number: TPS54427 Hi team
1. Could you share the measurement condition of Theta_JA for TPS54427DDA? Customer is wondering 42.1℃/W can be used at their condition, that is the 4 layer board.
2. How do they estimate the value of VFBTH at the 5~50 degree…
Part Number: TPS54427 Hi
Because the MOSFET are in the converter, the spec only show the SW(low side MOSFET) max voltage=22V.
We want to know the high side MOSFET max voltage=?
Thank you!
Part Number: TPS54427 Hi Team,
Can we use the part TPS54427 with input Supply 5 V is Possible.
In data shee VREG5 Regired the input range 6V<VIn <18V for the VREG5 OUT is 5.2 V
If Provide the 5 V VREG out is enough to bias and UVLO. Please clari…
Other Parts Discussed in Thread: TPS54427 We have questions about TPS54427.
In datasheet p.3, about VREG5 pin,
A capacitor (typical 1 µF) should be connected to GND.
Question 1.
Are there any wrong if we use 0.1μF in VREG5 pin?
Question 2. …
