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 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.
Are there any wrong if we use 0.1μF in VREG5 pin?
Question 2. …
Part Number: TPS54427 Hi
I got a question from my customer about TPS54427.
This device can change the soft start time to adjust the soft start time capacitance.
Could you tell me the available maximum capacitance of it?
Part Number: TPS54427 We wish to change the inductor and output capacitance values, which takes us off of the recommended values in Table 2 on page 12 of the datasheet. There is not much guidance on the limits of doing this, since the paragraph above…
Other Parts Discussed in Thread: TPS54427 , TPS54227 Our customer uses the resistance of EN as shown in the attached figure.
About TPS54427, does 225~900kΩ mean to RB?
And please tell me the recommended value of RB when VEN is 5V.
