Part Number: TPS92520-Q1 TPS92520QDADRQ1
There are difference epoxy coverage observations found. Kindly please advise is this acceptable and does it impact the form, fit function of the parts?
Shade is epoxy in die bonding.
Part Number: TPS92520-Q1 Hello expert,
Here is my test waveform. The left is before the SC event, and the right is about after the SC event.Pls check my question:
1.FLT keep on low before and after the OC.I know KLT low represent a fault detected…
Part Number: TPS92520-Q1 Hi Team,
Please help clarify whether it is normal when epoxy not fully covered on die paddle? will it affect the operation of the part?
As showed on Xray photos, Blue with epoxy 100% covered, while Red is without. Please advise…
Part Number: TPS92520-Q1 Hello expert,
I know when OC happened there are 3 cases as last discussion.
Now I have 4 questions:
1.Given an output voltage(for example 30V),how to set the input voltage? If input too high, the efficient too low; but if…
Part Number: TPS92520-Q1 The Low-side sinking current limit threshold in TPS92520 is typical 1.5A. When ILS is over 1.5A, fault will be triggered. As Buck converter, the low-side switch conduct the current when high-side switch turn off. If 1.5A(average…
Part Number: TPS92520-Q1 From the datasheet we know that A short failure is indicated when the CSNx voltage drops below 2.45 V. But when the output channel is switched off by set CHxEN=0 or pull down the UDIM, the voltage of CSNx is about 2V,which is…
Part Number: TPS92520-Q1 Hello expert, In my design the power coil is 47uH,current sample resistor is 0.1R.Input 30~60V,output 3~50V 0.1~1.5A.Tj -40~150C
Could you pls share the output current accuracy and calculation for this device?
Part Number: TPS92520-Q1 Hello expert,
About the FLT PIN (Open-drain fault indicator),what kind of defect occur will FLT pull low?
Can we read the associated status register bit instead of checking this FLT?
After the defect is removed, the FLT…
Part Number: TPS92520-Q1 Hello expert,
What is the different between we set CHxEN=0 and we pull down the UDIM PIN? I think UDIM just control the output current and the internal function will remain,but CHxEN=0 will not only disable the output current…
Part Number: TPS92520-Q1 Hello
I plan to apply the LMMS , so i check the file about the An ECU Architecture for Adaptive Headlights :LMMS
To select the correct LED drive i think i need to learn this acticle. but i have some question about this article…
