Descri ption
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 8-Lead SOIC
applications. Logic inputs are compatible with standard CMOS or LSTTL output, down IR2011S
to 3.0V logic. The output drivers feature a high pulse wrrent buffer stage designed for
minimum driver cttoss-aonduction. 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. Propri-
etary HVIC and latch immune CMOS technologies enable ruggedized monolithic con-
struction. 8-Lead PDIP

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