Alpha & Omega Semiconductor AOZ96779 | Demoboard AOZ5473

Description

The AOZ96779 is a high performance dual output digital controller designed to power high current loads, like Intel’s VR13.HC processors. All required parameters are programmable through the PMBus™ interface. The device utilizes digital technology to implement all control and power management functions in order to provide maximum flexibility and performance. NVM is integrated and is used to store custom configurations. The AOZ96779 can support up to 8 phases and allows programmable phase assignment between the two loops. The AOZ96779 supports Power State transitions featuring Pulse Skipping, and programmable Dynamic Phase Management (DPM) maintaining the best efficiency over all loading conditions, without compromising transient response. The device assures fast and independent protection against load over current, under/over voltage and feedback disconnections. The device is available in QFN-40L 5x5mm.
