TheAOZ5049QIisahighefficiencysynchronousbuckpowerstagemoduleconsistingoftwoasymmetricalMOSFETsandanintegrateddriver
The AOZ5049QI is a high efficiency synchronous buck
power stage module consisting of two asymmetrical
MOSFETs and an integrated driver. The MOSFETs are
individually optimized for operation in the synchronous
buck configuration. The High Side (HS) MOSFET is
optimized to achieve low capacitance and gate charge
for fast switching with low duty cycle operation. The Low
Side (LS) MOSFET has ultra low on-resistance to
minimize conduction loss. The compact 3.5mm x 5mm
QFN package is optimally chosen and designed to
minimize parasitic inductance for minimal EMI signature.
The AOZ5049QI is intended for use with TTL and tri-state
compatibility by using both the PWM and /or FCCM inputs
for accurate control of the power MOSFETs.
A number of features provided make the AOZ5049QI a
highly versatile power module. The bootstrap supply
diode is integrated in the driver. The LS MOSFET can be
driven into diode emulation mode to provide
asynchronous operation when required. The pinout is
optimized for low inductance routing of the converter,
keeping the parasitics and their effects to a minimum
