OZ8127 is a highly integrated DC/DC controller with integrated drivers comprising of a dual phase controller for the CPU core rail. The output voltages can be programmed from 0.5V to 3.04V through a high speed serial bus， compliant with the VR12.6+ specifications. By shorting BST2 to GND， OZ8127 also can work as 1 phase， which will be more suitable for low power requirement platform. Key parameters of the controller such as operating frequency， slew rate， maximum temperature can be programmed through an I2C port. Vboot voltage and maximum current registers can be one time programmed. The thermal pin TEMP can sense the highest temperature spot of power solution， and report the temperature zone to CPU. OZ8127 has full range of protections such as OVP， OCP， UVLO and OTP. Integrated boost diodes simplify the design and reduce the PCB area. Skip mode maintains a good efficiency for the power conversion， especially in light load condition.
