STEVAL-A6986IV3 grounding capacitors
Hello, I am strongly considering using the STEVAL-A6986IV3 based design for a 4 channel isolated gate driver power supply. One thing that looked strange in the the schematic was the four ground capacitors Cgnd1,2,3,4 which are 4.7nF 2000V rated. The...
Resolved! Questions about to Auxiliary power supply with VIPER06
HiI have a question about the conection of VIPER06 module as auxiliary power supply. I Have a power stage PFC with L6562 and two capacitor in series as outuput capacitor. Then, i need a 15V aux power supply. Can i connect the VIPER06 Flyback stage,...
Resolved! L6982C33DR & L6982C50DR always provide 2.5V output
Dear Community,I’m currently testing the L6982C33DR and L6982C50DR to supply 3.3V and 5V to my board.I followed the reference design provided in the user manual and completed the PCB layout accordingly.However, when I power the board with 12V (Power+...
l6235 brake issue
i have a design using the L6235 motor controller. when the motor is running at 4800 I applied the brake and disabled the enable pin of the IC, all worked fine, But i was getting the motor overrun because of the inertia of the gears.I tried to applied...
