AOZ5317NQI-04
AOZ5317NQI-04 is High-Performance DrMOS Power Module manufactured by Alpha & Omega Semiconductors.
AOZ5317NQI-04 High-Current, High-Performance Dr MOS Power Module
General Description
The AOZ5317NQI-04 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 AOZ5317NQI-04 uses a PWM input for accurate control of the power MOSFETs switching activities, is patible with 3 V and 5 V (CMOS) logic and supports Tri-State PWM.
Features
- 2.5 V to 25 V power supply range
- 4.5 V to 5.5 V driver supply range
- 60 A continuous output current
- Up to 80 A for 10 ms on pulse
- Up to 120 A for 10 µs on pulse
- Up to 2 MHz switching operation
- 3 V / 5 V PWM / Tri-State input patible
- Under-Voltage lockout protection
- SMOD# control for Diode Emulation / CCM operation
- Low Profile 5x5 QFN-31L package
A number of Features are provided making the AOZ5317NQI-04 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.
