Class D Audio Output MOSFETs
IR improves the performance capabilities of Class D audio amplifiers by offering the integrated Half-Bridge IRFI4xxxH-117P series of Class D Audio MOSFETs.
The integrated Half-Bridge package reduces the part count by half and enables better PCB layout. In addition to lower On-Resistance, the series of integrated Half-Bridge Class D Audio MOSFETs provide optimized Gate Charge and Body-Diode Reverse Recovery to improve key Class D audio amplifier performance parameters such as efficiency, THD and EMI.
The new integrated Half-Bridge Class D Audio MOSFETs family covers the entire mid-voltage range, from 55V to 200V, for mid and high power amplifiers.
Features at a glance:
Low RDS(on) for higher power density
Lower gate charge for higher speed
Single half-bridge configuration, with heatsink
Switching frequency = 400 kHz, Modulation Index = 90%, Vpeak factor = 10%
