Part Number: LM5113

The driven currents requirement of input port HI and LI is not given in the datasheet. How can i get this information?Can i diretly use the PWM signals from a CPLD port (with the maxim 25mA output) to drive a LM5113?Thanks in advance!

  • Hi Xdragon,

    The HI and LI pins are digital inputs with high impedance typically 1-2pf and 100k-300k pull-down, you will only see minimal current to this pins: a 25mA drive is more than sufficient to drive these pins.
