AOZ73004QI Datasheet | Alpha & Omega Semiconductors

Description The AOZ73004QI is a high performance multi-phase buck controller designed in pliance with NVIDIA Open VReg specifications. It provides one output rail and supports PWMVID interface. AOS offers a novel AOS Advanced Transient Modulator (A2TM). It bines an advanced variable frequency hysteretic peak current mode control with proprietary phase current sensing scheme for fast transient response and low system cost. The control loop enhances light-load efficiency by seamlessly entering DCM mode of operation. Autonomous Phase Management also assures the optimized efficiency and power loss during light load with single phase DCM mode. The AOZ73004QI provides plete protection including UVP, OVP, OCP and OTP. AOZ73004QI also offers real time telemetry information via IMON pin for output currents. The AOZ73004QI features are external reference input and PWMVID dynamic output voltage control, in which the output voltage is regulated and tracks external input reference voltage. The PWMVID duty cycle determines the variable output voltage at REFIN, Vmin is the zero percent duty cycle voltage value. Vmax is the one hundred percent duty cycle voltage value. AOZ73004QI can be paired and supports multi-sourced industry standard Dr MOS and Smart Power Stage (SPS). AOZ73004QI is offered in pact 4mm x 4mm 32-pin QFN package.
