Hello,Not sure that the product I'm looking for exist. It should behave like LED driver but after looked through different LED I didn't find a product that meet my requirements:can drive 1 ... 15 LEDs connected in serieshave a possibility to change c...
Hello i want to use the LD1084 voltage regulator . I need to build a decoupling networks on the inputs and outputs of it. Is there are some recomendations regarding decoupling networks of this noise. Or if you have spice model of this component? Than...
We have a +/-12V regulated power supply as part of our board design.The board takes a 5V input and passes this though a TI DCP020515DU DCDC. This gives us +/-15V unregulated. Each 15V rail has been tested with loads up to 60mA (our requirement is 30m...
Hi,I am facing a strange problem regarding the PDO2 output in STUSB4500. Inspite of setting PDO Number as 3 and configuring the PDO2 voltage and current values using the STSW-STUSB002 GUI, I am not able to get any voltage output at PDO2. The status L...
Hi. We need help to integrate wireless charging Capabilities to phone modules.Each phone will carry space for 2 magnetized modules.[ external battery / wireless earbuds / vaping ]Phone models are: s22 and 23 ultra 5g +( battery module to send power t...
Hello all,In the STDES-30KWVRECT Vienna Rectifier power circuit, 1. Relation between Q1 and Q2 switching pulses are IN-PHASE, likewise I want to know, How Q1 and Q3 switching pulses are related ?2. What PWM technique is used to generate switching pul...
I'm using SCTWA60N120G2-4 for one of my power management PCB. However, I saw there is copper exposed on the component leads. Base on IPC 610-H requirement, exposed basic metal on component leads is defect, but it seems to me the expose metal is manuf...
I believe this is a TRIAC based on the circuit it is in, but I cannot find any data on this device nor vendors having it in stock. It's a TO-220 package, could someone please explain the ST part numbering? Thanks!
I am trying to identify a transient voltage suppressor manufactured by ST that I need to replace.I have not been able to determine the correct product based on the coding found on the package. Would anyone here be able to identify this TVS?The coding...
Hello,I am using the STUSB4710AQ1TR to charge some USB-C devices at the default 45W. I am operating in a mode that's only charging (no data communication). To do this, I used the recommended application schematic provided in the datasheet. My input v...
