The F72830 is a quadro MOSFET drivers specifically designed to drive quadro power N-Channel MOSFETs as a four-phase linear regulators. The device contains under voltage protection for every linear controller, an external ceramic capacitor to adjust slew rate of soft-start, and integrated I2C interface. The built-in I2C interface provides the function to fine tune the output of every linear controller from 0.74V to 1.04V, 0.02V per step, and the default output is set to 0.8V.
The F72830 also offers 3 independent enable pins to control the corresponding linear controller. Linear controller 1 is active as power on, and other remained linear controller 2~4 are controlled by enable pin, EN2~4. Except being a regular linear controller, the F72830 can be paired with the chip, which contains AMD K8 power on/off timing sequence to be used a platform power supplier, for example, F71863, or any specific purpose. The chip is a 16pin SOP package and powered by 5/12V.
