AOZ5508QI

AOZ5508QI

DrMOS + Smart Power Stages (SPS)

AOZ5508QI is a 35A efficient DrMOS module in QFN3.5x4.5 package. It uses PWM and FCCM inputs for accurate control of the power MOSFETs switching activities. It is compatible with 3V and 5V logic and supports Tri-State PWM. The Low-Side MOSFET can be driven into diode emulation mode to provide asynchronous operation and improve light-load performance.
