6563CRZ - ISL6563CRZ
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
® ISL6563 www.DataSheet4U.com Data Sheet April 13, 2005 FN9126.6 Two-Phase Multiphase Buck PWM Controller with Integrated MOSFET Drivers The ISL6563 two-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors.
Multiphase power conversion is a marked departure from single phase converter configurations employed to satisfy the increasing current demands of modern microprocessors and other electronic circuits.
By distributing the power and load current,
6563CRZ 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 sin
