IR2111 Details

The maximum voltage rating of the IR2111 is 500V, but it can be used in applications up to 600V with proper design and layout considerations.
The bootstrap capacitor should be selected based on the switching frequency, output current, and voltage rating. A general rule of thumb is to use a capacitor with a value between 10nF to 100nF, and a voltage rating of at least 2x the maximum voltage of the high-side driver.
The VCC pin is used to power the internal logic and low-side driver of the IR2111. It should be connected to a stable voltage source between 3.3V to 15V, and decoupled with a capacitor to ensure proper operation.
Shoot-through current can be prevented by ensuring that the dead-time between the high-side and low-side drivers is sufficient, typically around 100ns to 500ns. Additionally, the layout should be designed to minimize parasitic inductance and capacitance.
The maximum switching frequency of the IR2111 is typically around 500kHz, but it can be used up to 1MHz with proper design and layout considerations. However, higher frequencies may require additional considerations for EMI and thermal management.
