Description
The IR2011 is a high power, high speed power MOSFET driver with independent high
and low side referenced output channels, ideal for Audio Class D and DC-DC converter
applications. Logic inputs are compatible with standard CMOS or LSTTL output, down
to 3.0V logic. The output drivers feature a high pulse current buffer stage designed for
minimum driver cross-conduction. Propagation delays are matched to simplify use in
high frequency applications. The floating channel can be used to drive an N-channel
power MOSFET in the high side configuration which operates up to 200 volts. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
