HI Sir,we have two different results of the ripple noisebase on same PCBA design, but different L7987 origin:1. Mark of "ST e3 G9207,L7987, CHN 3L0",ripple noise 2.2V 2.9KHzinput 24V, output 12V, load 5ohm 2.4A 2. Mark of "ST e3 7B658, L7987, PHL 037...
Good morning; I want to do a simple relay controlled by my nucleo board; so I did a simple circuit with the STP55NF06L; however, it does not work as expeted, in real ife, even when I am not sending voltage to the gate, the transistor conducts electri...
Hi! I need a SPICE model for T2535T-8I. I couldn't find it anywhere. Please help! Thank You!
Hi everyone,Good day!I'm currently working on modifying the Responder ID using CAN FD communication.I initially had a firmware running on an MCU that was capable of modifying the Responder ID. My goal now is to analyze the CAN FD communication from t...
Hello,I want to use 3x mentioned devices in a usb hub to deliver pover to peripherals.Does anyone has experience with something like this? Can it negotiate with three different devices or it will cuse some trouble.? Best regards, Mrdjoni
Hello,For the past few days, I’ve been trying to operate the VIPer35 quasi-resonant offline high-voltage converter, but I haven't been able to get any output. I attempted to bypass or disconnect the output of the PC817 optocoupler and also tried sho...
Hi, We have build a led driver circuit using STP40NF20 -- 2 nos in parallel, the issue i am facing oscillation issue in Drain pin (Vled ), So kindly support in this regards..
I have ST1PS02D1QTR (output discharge disabled variant). However, I am observing that if AUX = low but external 1.2V is applied to VOUT2, I get power dissipation that seems in-line with output discharge resistance on VOUT2. My question is this: does ...
We bought the following evaluation boards to test a wireless charging concept:STEVAL-WBC86TXSTEVAL-WLC38RXNow it seems that the datasheets of the evaluation boards and also from the chips that they use got pulled from the website. The control softwar...
A design I am debugging is utilizing Y5V dielectric capacitors on the input and output of the L4931. There is a 2.2uF capacitor directly at the output and another 2.2uF capacitor on the other side of an ~4 Ohm resistor that analog supplies are used o...
