AOZ97774QE Datasheet | Alpha & Omega Semiconductors

Description The AOZ97774 is high performance dual-channel digital controller designed to power processors, ASICs, or FPGAs. All required parameters are programmable through PMBus™ interface. The device utilizes digital technology to implement all control and power management functions to provide maximum flexibility and performance. It can be configured using PMBus or Pin-strap to select custom configurations stored in Non-Volatile Memory (NVM) and/or Read Only Memory (ROM). The AOZ97774 features up to 3+1 phase programmable operation. The device assures fast and independent protection against load over current, under/over voltage and feedback disconnection. In addition to being able to store the device configurations in the NVM, the device can hold up to 15 custom configurations in the ROM. These configurations and up to 31 output voltage settings can be selected by pinstrapping. The device is available in QFN-40L 5x5mm.
