About specification (Ips-pwm) of STBB2

What is the value of "Ips-pwm" in Table 6 of 5 Electrical characteristics?It is written on page 8 of the STBB2 data sheet.See attached file (_Ips-pwmjpg.) in details.Please answer in Japanese if possible.

Does a switching regulator effect the output of a buck converter with a fixed output voltage of +5 V like the L7805?

I'm trying to design an voltage regulator on a motor control board. I want an output voltage of 5 VDC and the input voltage is 24 VDC. Because of heat production i was thinking about using a switching regulator like the L7983 followed by an L7805. Bu...

Hi, what can I do with a L6235D to improve its thermal characteristics to reach max output current? Thanks

Good dayI am currently designing a BLDC driver, with the L6235D chip, ideally I wanted to use the L6235PD but there isn't any stock available.So basically I am concerned that the L6235D will not be able to drive my motor, the motor requires at least ...

we used STBC02 charger IC to charge 3.7V/ 60mA Li-Ion Coin Cell battery. we set the Ifast to 60mA and Iend set to 3mA. while charging it reaches Cell Max. Voltage 4.2V, and charging current 60mA to down to 7mA. it taking 7mA always.Pls.give solution

for It continuously taking 7mA current while charging.

I'm trying simulate STL100N10F7 in a circuit design in LTspice ad there are 3 models in the download file. I'm not sure which one to use. What are the differences? I don't see anything in the comments.

Resolved! hi and goodtime can I ask what this part is? really Is the code written on it w03? Or do I read it wrong? .please guide me. thank U so much

Can I request PCB File Altium or Eagle format of STEVAL-VP12201F?

This board have good layout and the layout fit to my application ? But I need move connector location. If I have PCB format. It will easy for me to finish my product.

STPM32: Is reactive power always calculated on fundamental ?

Is BLPFVx shown on figure 35 accessible to select wiht/without LPF ?

I am using LNBH26. I want to use the 22kHz tone amplitude as 400mV, but is there any function to change the amplitude?

I want to know if there are different housings used for BTW69-1200? I have 2 devices on my table and wonder if ST has used also a different housing and if there are any differences between the devices?
