STEVAL-ISA018V1 at 24V 8-10A
Posted on May 09, 2014 at 11:29Hi,I found an AC-DC evaluation board STEVAL-ISA018V1 which uses L6599 designed for 24V 6A with cut-off at 10A (thermal). I want to modify it for 8-10A (at 24V)operation. How to enhance the current rating? Which compone...
Viper16 Buck non-isolated
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...
PWM: drive output low in disabled mode
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 ...
prevent/avoid stall, L6470
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...

LED5000 high overshoot current
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...
L5972D often melting!?
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...
