TheAOZ5039QIisahighefficiencysynchronousbuckpowerstagemoduleconsistingoftwoasymmetricalMOSFETsandanintegrateddriver
The AOZ5039QI 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 MOSFET is optimized
to achieve low capacitance and gate charge for fast
switching with low duty cycle operation. The low side
MOSFET has ultra low ON resistance to minimize
conduction loss. The compact 5mm x 5mm QFN
package is optimally chosen and designed to minimize
parasitic inductance for minimal EMI signature.
The AOZ5039QI is intended for use with TTL and Tri-state compatibility by using both the PWM and/or FCCM
inputs for accurate control of the powerMOSFETs.
A number of features are provided making the
AOZ5039QI a highly versatile power module: The
bootstrap diode is integrated in the driver.The low side
MOSFET can be driven into diode emulation mode to
provide asynchronous operation when required.The pin-out is optimized for low inductance routing of the
converter, keeping the parasitics and their effects to a
minimum
