AOZ5117QI-02 Datasheet | Alpha & Omega Semiconductors

Description The AOZ5117QI-02 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. AOZ5117QI-02 es with low noise technology enhancement at switching node to reduce noise interference. The AOZ5117QI-02 uses a PWM and SMOD# input for accurate control of the power MOSFETs switching activities, is patible with 3V and 5V (CMOS) logic and supports Tri-State PWM. A number of features are provided making the AOZ5117QI-02 a highly versatile power module. The boot-strap diode 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.
