AOZ5049QI - DrMOS Power Module

Description

The AOZ5049QI 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.

Features

  • provided make the AOZ5049QI a highly versatile power module. The bootstrap supply diode is integrated in the driver. The LS 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 a minimum. Not Recommended for New Designs Replacement Product: AOZ5048QI Features.
  • 4.5V to 25V power supply range.
  • 4.5V to 5.5V driver supply range.
  • U.

AOZ5049QI High-Current, High-Performance DrMOS Power Module General Description The AOZ5049QI 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 (HS) MOSFET is optimized to achieve low capacitance and gate charge for fast switching with low duty cycle operation. The Low Side (LS) MOSFET has ultra low on-resistance to minimize conduction loss. The compact 3.5mm x 5mm QFN package is optimally chosen and designed to minimize parasitic inductance for minimal EMI signature.
