L6480 Stepper Motor Power Supplies Question

Posted on February 21, 2017 at 07:11Hello,I am looking at using the L6480 in the externally supplied modes, where my system will be supplying: VS = +24V DCVSREG/VCC = +12VVCCREG/VREG = +3.3VThe +24V supplied to VS by the system is removed (floating)...

help with the L6668

Posted on February 28, 2017 at 15:54i am looking at using the L6668 as a multy output flyback, i need it to have a high voltage start up (which this IC does have, that is good), but i also need it to synchronise it to about 100KHz from a micro.my qu...

Can the L6615 load share controller be used for 50V bus high side application? A resistor divider to reduce common mode can be used on the sense pins but how do you calculate the component values?

Posted on February 18, 2017 at 17:51I am using the L6615 in a 50V bus current sharing application and I have the required voltage divider from each side of the high side current sense resistor to ground but I am unsure if another series resistor nee...
