POWERSTEP01, When in external step mode, how does KVAL get calculated for VOLTAGE MODE?

I know that Vout = Vs * KvalI know that Kval = [(Kval_x * BEMF_COMP) * VSCOMP * K_THERM]*microstepIn the datasheet KVal_x is either KVAL_ACC, KVAL_DEC, KVAL_RUN, or KVAL_HOLDdepending on the state of the motion planner.But, I am not using the inter...

Problem with debug clear code STM32 NUCLEO

Hi. I have a question about the STM32 NUCLEO F334R8. I connected the usb cable to the computer, compiled the generated clean code, clicked debug and terminate and I have such an error. What can it be about?

Hello Would you please tell me about the expiration cycle L9741 and L9708 ?

Best way for enabling SWOUT_ON bit ?

Hello all,We made a custom board using stm32mp157 and stpmic. Board is booting, we're using openstlinux, we have prompt and so on.We'd like to use PMIC_SWIN / PMIC_SWOUT funtionnality (swin=5.2v). On the PMIC datasheet it say that we have to set SWOU...

can you share me 3D model of Power Schottky rectifier STPS20SM60D.

I have doubt while I am placing this part TO-220AC as a horizontal mount how much pad size I should use. heat sink pad exist on top or for full package on bottom side..

Dear All, I need information. Can you tell me if smd buck regulators and smd power diodes can have altitude related problems? Does these components continue to work well at 6500 m? Thanks in advance. Best Regards Stefano

In particular I'm interested in buck regulator L7985A, L6984TR and power diodes STPS10H60SFY and STPS360AFY.

L6562AT stopping when the load decreasing to full charge to 50%

I looh overvoltage when the load decreasing, moving the compensation components I have only and overvoltage of 5v, (normal voltage 400v), but the pfc continuos stop.Somme idea???

Customer applied -6.5V rather than +6.5V to RHFL4913 V+ pin in a design. V- was at ground. How robust is the regulator to a reverse voltage of this level? Event was less than 1 second in duration. System still works but there is concern about overstress.

STSR2P similar controller

i need controller similiar for STSR2P (secondary side synchronous rectification controller for forward topology). STSR2P has obsolete status so I need a new.
