LM3424 waveforms? DemoBoard
Hi, i tried LM3424 demoboard and adjust to me purpose. All works perfect, but when i design my PCB and i put all the components, the waveform and the efficiency of the system changes, the waveform of the transistor on the drenator pin is differents b...
interleaved active clamp flyback converter
as per the figure we provides a dc voltage as a input to the interleaved active clamp flyback converter block, provide a PWM signal to the MOSFET which is in interleaved block for switching purpose. PWM signal is generated by the microcontroller whic...
I connect stm32 F207ZG to usb port and the chip overheats. LD5 also is on and LD3 does not blink. What goes wrong?
I tried to download a program for motor control. I think that this is the potential problem because I use wait(1) instead of wait(0.1)
STC3115 fuelgauge not working when RSTIO + SCL + SDA is ZERO.
Hi I am having a strange issue with STC3115.My system is designed in such a way that the main MCU and all circuitry is powered using a push button controller. On long press my MCU and all devices will be off but except the fuelgauge which is powered ...
How can I turn off a PWM signal and turn on a High (one) in the same pin?
I´m using a PWM signal and the complementary with TIM1(timer1). The Pwm´s complementary singal is going out from pin A7 then I want to turn off the pwm signal from that pin and turn on a HIGH value (one) in the exact same pin (A7). The thing is that ...
We are using STPM32 metering IC for our application. We want to know the maximum current sourcing capacity of digital I/O pins, which is not clearly specified in the datasheet.

STEVAL-TSP004V2 configuration changes for 24V output
I recently obtained the STEVAL-TSP004V2 eval board, and tested it with Tripp-Lite NPOE-30W-1G injector. As supplied the eval board worked fine.I then modified the eval board as I require a 24V output, so :removed T5 and fitted a Coilcraft POE300F-24L...
Why VNH7040AY shuts off above 15 A immediately
Tested the VNH7040AYMounted on the official breakout board. (Also tried with custom PCB)Proper heatsink.50 and 100% 20 kHz PWM.With dummy load and also with real motor.Tried 7, 12, 20 and 24 Volt Vcc.Tried 3.3, 5 and 7 Volt control signal (INA, INB, ...
Why is the voltage high?
I’ve bought 1000+ L7805CP voltage regulators. On all the data sheets it say there is a +-10% voltage tolerance yet the voltage I’m getting is +55%. It says it’s input voltage range is 35v - 7v and its output is a nominal 5v (4.5-5.5v) yet I’m getting...
Problem calculating snubber component values for triac drive yields negative resistor?
I've tried to make a 24VAC triac switch driven by a triac optocoupler. It doesn't seem to be turning on fully. Direct connection of load to 24VAC measures .24amps but through the triac when on is only .13amps.I've gone back to the drawing board using...
