The maximum voltage rating of the bootstrap capacitor is typically 15V to 20V, but it's recommended to check the capacitor datasheet for the specific voltage rating.
The bootstrap capacitor value can be calculated using the formula: CBOOT = (VCC x tON) / (ΔV x fSW), where VCC is the supply voltage, tON is the on-time of the high-side switch, ΔV is the allowed voltage droop, and fSW is the switching frequency.
The recommended dead-time between the high-side and low-side switches is typically around 100ns to 200ns, but it may vary depending on the specific application and switching frequency.
Yes, the IR2117STRPBF can be used for synchronous rectification, but it requires additional external circuitry to control the low-side switch. The IC is primarily designed for asynchronous rectification, but it can be adapted for synchronous rectification with proper design and layout.
The maximum current rating of the IR2117STRPBF is not explicitly stated in the datasheet, but it's typically limited by the package thermal resistance and the maximum junction temperature. A safe operating current is typically around 1A to 2A, but it may vary depending on the specific application and thermal design.
