AOZ5019

High-Current, High-Performance

DrMOS Power Module

General Description

Features

The AOZ5019 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

 4.5 V to 25 V input voltage range

 4.5 V to 5.5 V driver supply range

 Up to 30 A output current

 Up to 1.5 MHz PWM operation

 Tri-state PWM input

 Undervoltage protection

to minimize conduction losses.

DS(ON)

 Integrated boot supply diode

 Diode Emulation mode of operation

 Small 5x3.5 QFN-23L package

The AOZ5019 is intended for use with TTL and tri-state

compatible, which allows both power MOSFETs to be

turned off.

Applications

A number of features are provided making the AOZ5019

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 pin-out is

optimized for low inductance routing of the converter

keeping the parasitics and their effects to the minimum.
