Hello everyone,we are currently trying to bring up the L6591 without PFC, but unfortunately we have not been successful so far.It looks like the L6591 is not able to start up correctly.The Vcc voltage slowly rises to about 14V with the built-in HV s...
I am selecting the LD1117S50CTR. The package is SOT-223.I understand that the thermal resistance Rthja = 110 °C/W shown in the datasheet is the value for the IC alone.Since I am designing the PCB, I would like to know the relationship between copper ...
Translator I would like to identify the following two diodes, please.
Hello, The datasheet doesn't seem to mention the function the tab on the back of the IC. Can I connect it to GND to thermally conduct the heat out? Thanks
Hello! I am designing a wide input range flyback converter using the altair04-900 for my formula student team.For testing the switching behaviour, I simulated the ALTAIR04-900 using the schematics in the datasheet of figure 4-7. figure 4-6 shows resu...
Hi ST Micro,Please send me the information for the adjustable LDO output voltage desgined from R1 and R2 formula.
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...
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...
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...
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 ...
