PowerSTEP01 Low speed optimization
I cannot see the effect of the low speed optimization.I set speed to 1 rpm and watch the phase currents.With these settings (these values are readbacks):min_speed: 0x1fdfconfig: 0x2c90step_mode: 0x0007I get significant distortion around 0 A:To compar...
PowerSTEP01 self-contradicting datasheet
The PowerSTEP01's datasheet says on page 34 that MIN_SPEED is 12 bits wide.On page 37, it is described as 13 bits wide.I suppose that 13 is correct, from code I've read online, but a confirmation (and fix) would be nice. I cannot see the low speed op...
Test result data for 5V output device LDK220U50R
Hello Team,We have selected part no: LDK220 and LDK320 with a SOT-89 footprint for one of our applications. We have referred to the complete datasheet, but we have not found the test results for 5V output category devices, like the voltage dropout of...
STEVAL-ISD01KCB
I've been looking at the STEVAL-ISD01KCB, and I saw in an image that it has some capacitors between pins 8 (-DC) and 9 (+DC). What is the value of that capacitor? Is it necessary to include it? I ask because I've noticed that this capacitor slightly ...

I have design Buck converter with Viper318HD ,With below specification:Vin:(85 to 265)VACVout=12VDCIout=500mAAnd i not follow recommended Commponents value which Are mentioned in Edesign tool, i use components which are availble with me....
Is it possible to parallel multiple STEF01 e-fuses?
I have a design running on 24V SLA batteries using STEF01 fuses for protection of the lower powered rails and an LT4356 using external MOSFETs for a 25Amp rail. That 25A rail is giving me headaches. Staying within the SOA of the MOSFETs is not that e...
power source
Hello, (L6562DTR)I have encountered some problems when using this chip and hope to get some suggestions from you； ”The PF output voltage of 480V FC load is 0.7435“ The power input voltage is 250V-528VAC, with PFC+ flyback. The PFC BUS voltage is 7...
Looking for STWLC89 datasheet
Looking for datasheets for the STWBC2HP and STWLC89, do these exist? I can't find them anywhere on the internet
Change PDO3 to 15V, 1.5A don't work
Hello Everybody, I'm new in this place. I use an Evalboard ISC005V1 with STUSB4500 and an dedicate MCU to manage I²C port. I wanted to change the configuration of the PDO3 from 20V to 15V. I select PORT3 ( write 3 in 0x70 register ) I configure DPM_R...
