I bought STEVAL-ISC005V1 evaluation board from digikey, used DA45C-J3WEU usb c type from artesyn embedded technologies.(Capable for providing 15V/3A)When i connected adapter, i got 19V from VSINK and PDO3, but i didn't get 15V from PDO2, led is not ...
HelloI am using IHM06A1 driver with STM32F401RE to control stepper motor. I am supplying 5v and 0.300A for motor (according to motor datasheet ) using DC Power Supply and providing 3V/5V to IMH06A1 from STM32F401RE board. There is voltage drop at tim...
I have been working with the STSW-SPIN3202 library with the STEVAL-SPIN3202 and am unable to spin the Bull Running BR2804 above 8900rpm. I would like to have full speed control from 0-100% duty cycle but something is limiting the speed. Software deve...
We have been using the LED2000 and LED2001 for years with great success. We have a new design where it is possible that the LED loading the output can be disconnected during operation. The LED would be running around 1.5A. That would result in a swit...
Hi all,The LED6000 has a seperate EN and DIM line. I would like to use the dimming feature and also be able to disable the device. It seems I could use DIM only, and tie EN to VCC. Then, if I hold DIM low, the device should be disabled. As I use mult...
Hi,Looking at the PM8805 PoE Controller datasheet fig 7 and also AN5207 page 30 there is a 3M3 resistor from power ground to chassis ground. What it purpose, is this some form of bleed resistor to stop voltage build up? My main question though is why...
my customer ordered TIP122 from Arrow and we only rec'd the delivery note. Can you provide the mfg cofc?
Hello,I am looking for a reference design for a PFC with an input range: 300V - 400V RMS.The output power should be 180W. Thanks.
I would like to find out the Transformer code size, gap, primary turns, secondary turns, leakage inductance and primary inductance.Thank youClaude Arpin
I plan to use STNRGPF01 to buil a PFC, eval board comes with 2 74HC132 package that are quit huge regarding the STNRG size. I would prefer to use single gate and TRUE D flip flop with set reset... knowing precise timings for Set and Reset will be a g...
