Hi, As you know, the way that the dummy load resistors are wired for an EMC test can actually drastically effect the scan....the common mode noise can radiate off the dummy load wires , and indeed, from the dummy load resistors. Why did you not choose a more tight layout

Hi, Can we put both os these on the same heatsink? Would it give noise issues.

Hi, Please assist us in finding a DER report of a HiperPFS Boost PFC that uses sendust torroids (or other torroids)? We only see ones using ferrite core half type, with the associated bobbin. Why is this? Can't HiperPFS manage the non linear inductance of a torroid inductor?

Hi, Our load can be 300W, but at most for 5 seconds. The Load duty cycle is 0.26, so the average power is only 80W Vin = 100-265VAC, Vout = 37V Do you believe the HyperPFS PFC followed by the HyperTFS 2 tran forward is the way to go? We

Hello! I have a question regarding the aforementioned LED Driver. I am currently designing a circuit to drive LEDs, with 230VAC input, and 32V/280mA output for the LEDs. In order to better understand the function of the driver, I took a look at the DER-515 demo board for it. My

Hello, I was not able to find any documentation in the Inno3Pro datasheet for following PI_COMMAND registers : #define INNO3PRO_LOOP_SPEED_1 0x32 #define INNO3PRO_LOOP_SPEED_2 0x34 As there is no documentation in the datasheet, there are also some magic numbers in the library code, which are not clear to me : #define

Hello, i have two questions regarding I2C communication with Inno3Pro. 1. ) Read back PI_COMMAND registers It tried to readback PI_COMMAND registers (e.g. 0x10 - CV) without success so far. Datasheet and innoswitch3-pro-mcu-library only cover readback of telemetry registers (READ10-READ15). There is no example with an I2C transmission diagram for

Infineon makes a full bridge EconoDUAL module, F4250R17. PI makes plenty of gate drivers for the half-bridge module. Are there plans or designs for a dual- or quad-channel gate driver to support this full-bridge EconoDUAL package? Thanks.

I am using LNK626 as a flyback converter. The output is Non-Isolated 5V. So can I use feedback from DC side instead of AC side of the output diode? I think I will get better regulation, because diode drop variation will be eliminated.

Hi I am using the above Inn3678 for a 60W power supply, from a PFC which will supply 385V nominal. The main output is 12V I did not initially realise that the SR gate drive was only 4.5V so had a MOSTFET which did not turn on well enough at
