Posted on April 23, 2014 at 16:19I have followed the Viper16 design tool and have followed the recommended components. The result is a voltage that is lower than expected (4.5v when expecting 5v) and dropping voltage as current increased from 5mA to...
Posted on April 15, 2014 at 17:57I'm using TIM1 for a 6-step motor control on a STM32F2xx. According of the table 4 in DM0004234 application note, I update OCxE and OCxNE at each commutation, to select a new step. When OCxE = 0 and OCxNE = 0, the ou...

Posted on April 26, 2014 at 08:51Hi, We have already design 12 volt 360mAmp current output non isolated power supply. But rigth noe we have increase current capacity in our exiting design. please let us know how to increase current capacity and how ...
Posted on April 25, 2014 at 17:09We want to run the stepper with as little current as possible. But then there's the risk to loos step if hoigher torque is neede (becuase of dust, friction,...). Is it possible to detect higher torque and increase ph...
Posted on April 21, 2014 at 15:48I am looking for a PCB footprint for the L6229Q VFQFPN 5 x 5 x 1.0 32 lead 0.050 pitch package. Is there a footprint available that has been used successfully and is available to download anywhere?
Posted on April 18, 2014 at 09:17Wurth has ready transformers for AC/DC supplies for 12V, 24V and 48V for 150W, 200W and 250W ratings. The details can be found here: http://katalog.we-online.de/en/pbs/WE-LLCR?sid=f6723a16ca Can these be used readily...
Posted on April 17, 2014 at 15:29Hi,I am using LED5000 to drive 6 Luxeon Rebel blue LEDs (2 parallel of 3 LED in serial) at 700mA. The dimming frequency is 1 kHz. The overshoot current is ~100mA. How can I lower down the overshoot current? The circ...
Posted on April 16, 2014 at 17:55Hi, I've made several DC-DC using L5972D. Sometimes it was blowing, but I supposed I made some mistake during soldering. Now I'm making 5V-1,5A power supply. I used same schematic on first page of datasheet (I used 2...
