Looking for TLE8080 and TLE8080-3EM reference design for 2 wheels bike.
Hello,
In which situation shold we change the SBC to the stop mode?
Hi Infineon Team,
I have used ICE2HS01GXUMA1 chip for LLC converter design for 54V output Voltage and 40A output current.
I have facing issue with output Voltage controlling. Actual output voltage coming 58V at load and also showing up to 2V variation at both the sides.
I have controlled the output voltage at 54.6V by controlling the optocoupler collector current using the adjustment of the optocoupler LED series resistor. But still showing voltage variations.
I have also facing issue with the output voltage regulation. It is working good up to 1A but above 1A voltage suddenly goes to zero volts.
I have tried for voltage regulation by adjusting the Rfmin resistor value, Rreg resistor value and optocoupler LED series resistor value. But still facing same issues means no improvement.
This is design for 350KHz resonant frequency and according to calculations minimum switching frequency is 332KHz and maximum switching frequency is 410KHz.
I am unable to select the Rfmin and Req Resistors value because in the graph it is given up to 260KHz only. As per below details.
I have another questions converter works in DCM mode up to 2A. At what load it will come in CCM mode.
Design specifications given below.
So I request please help for below point-
- Controller will work up to 450KHz switching frequency.
- What will the Rfmin resistor value for minimum switching frequency at both 332KHz and 337KHz. Can you please share the extended graph for frequency vs Resistor up to 450KHz.
- What will be the Req resistor value for maximum switching frequency at both 410KHz and 440KHz.
- How to achieved the 54V at no load.
- How to achieved the regulation up to 40A load current.
- At what load converter will come in CCM mode. It working in DCM mode up to 2A. Can we select some values for converter always working in CCM mode only at no load and full load.
- My tow Gan FETs blast during testing. I am unable to understand why is it happing.
I have already raise the tickets for this issue. But not any proper support at all.
Thanks & Regards,

Show LessI have been testing with this board using a 5R resistor on channel 0, when I set up a basic configuration and enable the chip (even at 0.00 amps current). I get an overcurrent Detection on Diagnosis Error Register 0, OC0. This turns off the channel until the the register is cleared.
This doesn't happen when I use a Solenoid, an LED, or two 5R resistors in series for a total of 10 ohms.
1. Is there a minimum resistance that I need for this chip to function?
2. If I am trying to run constant current, and the chip is set at 0x0 or no current, why would I get an over current detection at all? Shouldn't the chip never trip the over current fault if it is truly constant current?

Hello,
In order to configure the features of XDP710 evaluation board by using XDP Designer graphical user interface (GUI), I need a license file. Could you please inform me how I can get it ?
Best regards,

While programming into the NVM of IR38363 controllers, we are getting the the error - "Please load the latest version of Config file for Manhattan SVID". Screenshot is attached. Kindly let us know what needs to be done.

Show LessHello,
Is there a register map for use with programming the IR38164 using I2C?
The PMBus commands do not appear to map directly to register map from what I can see trying to read back MFR information, and I would like to program this part using I2C.
Thanks,
James Cyndari
Show LessThe following figure measures the BUCK baud graph of TLF35584, may I ask why there is a sudden phase increase after 880KHZ? The portion of the graph boxed out in red # TLF35584

Show LessIs it possible to set the polarity of the WK pin on the TLE9461ES to HIGH active instead of LOW active?
If it is yes, which register should I set?
