Does this code work correctly to control a dc-dc converter?

Hi guysI want to control a DC-DC converter with a PI controller and STM2F103 MCU; first, the ADC unit reads input and output voltage and inductor current, then we have two control loops; voltage control loop and current control loop. For the PI contr...

What is the cause of spur near 1KHz when using LNBH26 power?

STC3115 RelaxCurrent Value I would like to know more information about this value because in the driver this define by tha capacity of the battery / 20 and in the AN4324 is /10 !!! What is the goal of this value ? Best regards David

Behaviour of STATUS pin at the VNQ860-E device?

Is the STATUS pin at the VNQ860-E device an input or an output. By reading the datasheet I am a little confused, because the function of the the pin is not really in-depth explained.

ST1S40 Max Current Problem On Different DC Sources

I made an DC-DC buck with ST1S40 in the simulations my output current is normal max 3A but in PCB i cant Load with 3A while using Chroma 6703.When i use my normal DC power supply i can Load with 3A and its not collapsing.I use GWINSTEK PEL-3041 Elect...
