Description
The IRS2011 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 appli-

cations. Logic inputs are compatible with standard CMOS or
8-Lead PDIP
8-Lead SOIC
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.
