Limit current to pins on LM5118 so smaller creepage rules can be used.
Vin = 9V to 40V. Vout = 12V, Iout = 2A.
I would like to limit the current going to certain pins on the LM5118 to allow for the small spacing between pins on the device.
The pins that appear to be a concern are Vin, Vout and HS.
For Vout I would like to put a 500 ohm resistor in series. I am not sure what the current over the resistor will be and how this may affect the emulated current mode.
For HS I would like to put a 500 ohm resistor in series. This appears to be a reference for the high side gate driver. Are their any concerns with adding resistance here?
For Vout I would like to put a 200 ohm resistor in series. Datasheet shows a current of 40mA on this pin. This would result in significant voltage drop. Perhaps for this pin an LDO with current limiting could be used.
Could you please provide feedback on the above pins and the affect the series components might have?
