Efficiency
Fig 9 shows efficiency characteristics of the IRAUDAMP8. The high efficiency is achieved by
following major factors:
Secure dead-time provided by the IRS2093, avoiding cross-conduction
Thermal Considerations
With this high efficiency, the IRAUDAMP8 design can handle one-eighth of the continuous rated
power, which is generally considered to be a normal operating condition for safety standards,
without additional heatsinks or forced air-cooling.

1) Low conduction loss due to the DirectFETs offering low R
2) Low switching loss due to the DirectFETs offering low input capacitance for fast rise and
fall times
