This is the datasheet of the driver IC I am working on (LM5112).
Following is the application diagram of the module.
Basically this is the GATE driver circuit for the MOSFET with PDM signal as the input.
I am looking for how to calculate value of the MOSFET input resistor (R3) ?
MOSFET input voltage (VDS) = 10V
Output power required is 200W.
1) How to calculate the MOSFET input resistor?
2) What are the factors affecting the MOSFET input resistor calculation?
3) What will be the maximum, minimum resistor value possible and effect in the circuit if the resistor value is changed (Increased or decreased) ?
Please let me know if any further info is required.
