AOZ5066 Datasheet | Alpha & Omega Semiconductors

Description 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 patible 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 patible 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...
