My customer has questions about TPS54240-Q1. Could you tell me about questions?
[Question] My customer want to change swithing frequency by external clock. ex. 400kHz -> 500kHz
1) Is there any specific about…
Naveen,
You are probably operating in Low Voltage Dropout condition. See this document:
It applies to TPS54240-Q1 as well. Let us know if this addresses your issue.
Hello Dhimat,
We do not have any dual switchers with integrated fets rated to 40V.
Our dual integrated fet switchers, like TPS55386, are only good to 28V.
For single switcher with integrated fets see:
TPS54540 TPS54040A TPS54140A TPS54240 TPS54340…
Part Number: TPS54240 about equation 2 & 3 of page 15 of TPS54240 datasheet
R1=(Vstart-Vstop)/Ihys
R2=Vena/((Vstart-Vena)/R1+I1)
Q1:
What is Vstart, Vstop and Vena?
Q2:
If I want to design a power application about 37V~40V input and 34V 1A output…
Other Parts Discussed in Thread: TPS2513 , TPS54540-Q1 , TPS54240 Hi,
I am using TPS54540-Q1 and TPS2513 for "idevice" charging. It works fine with iPhone 5/5S/iPad2 but iPad Air shows "Not Charging". I am testing with 2100mA divider mode (2.0V/2.7V) and…
Other Parts Discussed in Thread: TPS57160-Q1 , TPS54240 , TPS54260 Hi
I am considering using the TPS57160-Q1.
Vout is 5.625V ,switching frequency is 400kHz and inductor ripple current is 100mVpeak.
Usually it is used in Vin12V, but that worst case Vin is…
