HIP6601A INTERSIL [Intersil Corporation], HIP6601A Datasheet - Page 8

• Manufacturer Part Number: HIP6601A
• Description: Synchronous Rectified Buck MOSFET Drivers
• Manufacturer: INTERSIL [Intersil Corporation]

Since both upper and lower gate capacitance can vary, Figure 8 shows dissipation curves versus lower gate capacitance with
upper gate capacitance held constant at three different values. These curves apply only to the HIP6601A due to power supply
configuration.
