TheAOZ5066isahighefficiencysynchronousbuckpowerstagemoduleconsistingoftwoasymmetricalMOSFETsandanintegrateddriver
The AOZ5066 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 has low
capacitance and gate charge for fast switching with low
duty cycle operation. The low side MOSFET has ultra low
RDS(ON)to minimize conduction losses.
The AOZ5066 is available with two PWM options.
AOZ5066QI is intended for use with TTL compatible
PWM inputs. AOZ5066QI-01 has lower thresholds on the
PWM signal and can operate with 3V inputs. All other
parameters are identical for the two versions. Both
versions are tri-state compatible that allows both power
MOSFETs to be turned off.
A number of features are provided making the AOZ5066
a highly versatile power module. The boot supply diode is
integrated in the driver. The low side 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 the minimum
