AOZ5006

35A DrMOS Power Module

General Description

Features

The AOZ5006 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 16V input voltage range

4.5V to 5.5V driver supply range

Up to 35A output current

Up to 1 MHz 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 AOZ5006 is available with two PWM options.

AOZ5006QI is intended for use with TTL compatible

PWM inputs. AOZ5006QI-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 AOZ5006

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.
