AOZ5066

60A DrMOS Power Module

General Description

Features

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

 Fully complies with Intel DrMOS Rev 4.0 specifications

 4.5V to 25V input voltage range

 4.5V to 5.5V driver supply range

 Up to 60A output current

 Up to 1MHz PWM operation

 Tri state PWM input

to minimize conduction losses.

DS(ON)

 Undervoltage protection

 Integrated boot supply diode

 Diode Emulation mode of operation

 Thermal shutdown alarm with flag

 Small 6x6 QFN-40L package

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.

Applications

 Servers

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.

 VRMs for motherboards

 Point of load DC/DC converters

 Memory and graphic cards

 Video gaming consoles
