Posted on March 13, 2018 at 11:46I want to design Qi wireless receiver with 7.5W output capacity. I will use device STWLC03JR.Can anyone suggest me compact designing criteria or specification for Induction coil.I have seen they are readily available...
powerstep01 spi baudrate setting problem
Posted on March 09, 2018 at 14:05Hello,we tried to communicate to the powerstep01 trough spi and with a baudrate of 500kHz everythink works fine.The problem occur if we set the baudrate above 500kHz. Then we lose the first bit of each byte.For examp...
ST1S14 Vout=22v issue at Vin close to Dutycycle max
Posted on February 16, 2018 at 16:50Hello!I am facing a problem with ST1S14. Conditions: - if Vin is 24.5V or less and load current less 30mA, output voltage drops to about 15V. (Problem)- If Vin becomes about 16V and less and load current still les...
