8.2.1.2.1 Power Supply Components (R1 C1,) Selection

The LM5050-1 VS pin is the main supply pin for all internal biasing and an auxiliary supply for the internal gate drive charge pump. The series resistor (R1) value should be low enough to keep the VS voltage drop at a minimum. A typical series resistor value is 100 Ω. The capacitor value (0.1 uF typical) should be the lowest value that produces acceptable filtering of the voltage noise.
