6563CRZ Product details

Description

VCC (Pin 8) Bias supply for the IC’s small-signal circuitry.Connect this pin to a 5V supply and locally decouple using a quality 0.1µF ceramic capacitor.GND and PGND (Pins 25 and 14) Connect these pins to the circuit ground using the shortest possible paths.All internal small-signal circuitry is referenced to the GND pin.LGATE drive is referenced to the PGND pin.PVCC (Pin 16) Power supply pin for the MOSFET drives.Connect this pin to a 5V supply and locally decouple using a quality 1µF c

Features

of this controller IC include programmable VID codes compatible with Intel VRM9, VRM10, as well as AMD’s Hammer microprocessors, along with a system regulation accuracy of ±1%. The droop characteristic, used to reduce the overshoot or undershoot of the output voltage, is easily programmed with a single resistor. Important features of this controller IC include a set of sophisticated overvoltage and overcurrent protection. Overvoltage results in the converter turning the lower MOSFETs ON to clamp.
