AOZ97774QE集成電路（IC）的電源控制器監(jiān)視器規(guī)格書PDF中文資料

General 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.
