AOZ5318UQI - High-Performance DrMOS Power Module

Description

The AOZ5318UQI 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

  • are provided making the AOZ5318UQI a highly versatile power module. The bootstrap switch is integrated in the driver. The Low-Side MOSFET can be driven into diode emulation mode to provide asynchronous operation and improve light-load performance. The pin-out is also optimized for low parasitics, keeping their effects to a minimum. Features.
  • 2.5V to 25V power supply range.
  • 4.5V to 5.5V driver supply range.
  • 65A continuous output current - Up to 80A with 10ms on pulse - Up to 120A.

AOZ5318UQI High-Current, High-Performance DrMOS Power Module General Description The AOZ5318UQI 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 is optimized to achieve low capacitance and gate charge for fast switching with low duty cycle operation. The Low-Side MOSFET has ultra-low ON resistance to minimize conduction loss. The AOZ5318UQI uses a PWM input for accurate control of the power MOSFETs switching activities, is compatible with 3V and 5V (CMOS) logic and supports Tri-State PWM. A number of features are provided making the AOZ5318UQI a highly versatile power module.
