Hello IFX partner,
For TLE7259-3GE, "Suitable for 12 V and 24 V board net"
It is currently used in 24V systems, the maximum supply voltage will up to 48V, and after a while everything is normal for communication test. But the Max value is 40V in data sheet, Is it risky to use it this way?
If yes, Could you give us the suggestions for improvement? thanks a lot!Show Less
I am working with development kits TLE9015DQU AND AURIX TFT boards. Going through the manual, it states:Select the *.hex file “Infineon_TLE9015DQU_TLE9012DQU_TC265.hex” stored on MyICP.
Where to find the hex file? or is it available publicly?
How to prevent some copycats read the patch bin file data which has been stored to OTP in the XDPP1100 controller via I2C or other communication interface? Or any advice on the firmware security issue? Thanks!Show Less
Can you help me please.
I use QSPI to communicate between TC36x and TLE9471-3ES
I can't understand the difference between Status Information Field and Data bits.
In which case should I read the status information and the data field, for example :
To read the wakeup reason using the WK_STAT_0 register ( ADDR register = 0x46), I receive 0x0001 then the status field (0x01) and the data 0x00.
what do I use to read the wakeup reason, is it on the status field or data field? and why, please?
Could you explain the difference between reading the data and reading the status?
Could you please clarify.
Thank you and best regardsShow Less
i have designed and developed a 24V 3A CV power supply board on ICL8810.
The design requirements are
1) input 100-300V AC
2) output 24V 3A
3) PF > 0.95
4) THD less than 10%
5) Efficiency > 90%
6) Load and line regulation < 3%
I am sharing the schematic.
On turn ON, the voltmeter reads 24.045V - 230V input - no load
on setting load to 100mA the output is 23.96V
on 200mA its 22.93V and then right upto 1.2A its 22.9V
above 1.2A the output stops dropping.
at 1.7A its 18V
at 2.0A its 9V
I have checked everything but am not able to find the reason.
The transformer is as below
PQ2620 Ae 118
pin 3-1 primary 40T 0.35 x 2
pin 12-7 secondary 8T 0.35x4
pin 6-4 aux 5T 0.3x1
I have used the secondary output to TL431 directly, rest everything is used as per the ICL8810 Eval board guidelines.
would seek help to understand the load regulation issues and methods to diagnose and correct.
schematic is attached.
- According to the IEC TR 62380 formula provided below, might I get your assist to obtain the value of λ based on the parameters λ1 and λ2 from the document avove? follow as ~
IEC TR 62380 BFR formula:
OpenPower, i am unable to flash XDPE132G5D
Both dongle and chip were purchased form mouser.
I am able to flash IR35217 using same dongle with PowerCenenter so dongle is working.
Any attempt to flash the chip ends in error.
I am loosing flashing attempts.
Any help ?
I am using the REFWLCTX15WC1 reference design with the source code given from Modus Toolbox and I am trying to limit my output transmitter power to less than 6W. I have a power receiver that requests for 10W in BPP mode, so the power transmitter is outputting 8W in BPP mode which is causing an OTP event. I know where to limit the voltage on the Vbridge in the config.xml file in the source code. But when I limit the voltage to 5.5V, the current increases to 1.5A to produce that 8W output again. Unfortunately, I don't have control of what the power receiver is requesting. So, I am attempting to limit the power transfer on the transmitter side. Any help or suggestions will be greatly appreciated. Thanks!Show Less
now I need design the request as follow:
output current: 10~100A /constant current
output volotage: 2~9V
can you introduct the design or the part?Show Less
