In conjunction with two external MOSFET and a few external components, a complete Class D audio amplifier with protection can be realized. International Rectifier’s proprietary noise isolation technology allows high current gate drive stage and high speed low noise error amplifier reside on a single small silicon die. Open elements of PWM modulator section allow flexible PWM topology implementation 3 www.irf.com © 2013 International Rectifier October 24, 2013 IRS2092 Simplified Block Diagram FLOATING INPUT CSH VAA VB HIGH SIDE CS COMP IN- VAA+VSS 2 HO OTA GND HV LEVEL SHIFT COMP HV LEVEL SHIFT VS HV LEVEL SHIFT FLOATING HIGH SIDE VCC VSS DEAD TIME CSD HV LEVEL SHIFT PROTECTION CONTROL SD LO DT COM HV LEVEL SHIFT VREF LOW SIDE CS OCSET DT Typical Application Diagram 47 kΩ 2.7 kΩ +B BAV19WS 10 µF Vin 510 1 nF 1 nF 2 GND CSH VB 16 15 3 IN- HO 14 4 COMP VS 13 5 CSD VCC 12 10 µF 6 VSS 7 VREF LO 11 COM 10 DT 9 IRF6645 10 kΩ MURS120 10 Ω 22 µF IRF6645 10 µF 10 µF 10 Ω 3.3 kΩ 8 2.7 kΩ OCSET IRS2092 35 V 22 µH 0.1 µF 0.47 µF 4Ω Vout 1Ω 0.1 µF Vcc 8.2 kΩ 1.2 kΩ 150 pF 33 kΩ 10 kΩ 1 kΩ 3.3 kΩ 1 nF 10 µF VAA 4.7 Ω 1 12 V 35 V 8.2 kΩ -B 4 www.irf.com © 2013 International Rectifier October 24, 2013 IRS2092 Qualification Information Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model Charged Device Model IC Latch-Up Test RoHS Compliant †† Industrial (per JEDEC JESD 47E) Comments: This IC has passed JEDEC’s Industrial qualification.

GND input voltage is limited by IAAZ and ISSZ. VSS ramps up from 0 V to 200 V. Output logic status may not respond correctly if input pulse width is smaller than the minimum pulse width. www.irf.com © 2013 International Rectifier October 24, 2013 IRS2092 Electrical Characteristics VCC,VBS= 12 V, VSS=VS=COM=0 V, VAA=10 V, CL=1 nF and TA=25 C unless otherwise specified.
