Notes : 1. Versus Pin 4.

2. The output current can reach 4A peak for t ≤ 10µs (up to 200Hz).

3. Provided SOAR is respected (see Figures 1 and 2).

4. Equivalent to discharging a 100pF capacitor through a 1.5kΩ serial resistor / 200pF capacitor through 0Ω resistor.

5. This will occur during 1st half of flyback pulse.
