IRUK3055CQ01
POWER MANAGEMENT CHIPSET FOR
3-PHASE VRM 9.0 CONVERTERS
FEATURES
Complete VRM 9.0 chipset for a 3-phase Buck con-
verter capable of up to 60A
Optimized chipset for easy design of high current
multiphase DC-DC converters complying with the
VRM 9.0 specification
HEXFET® MOSFETs for the control and synchro-
nous FET socket
APPLICATIONS
Intel Pentium 4 and AMD K7 CPU Power
Low voltage/high current DC to DC converters
DESCRIPTION
The IRUK3055CQ01 is a complete power management
chipset solution that meets Intel’s VRM 9.0 specifica-
tions for CPU power. The chipset consists of the
IRU3055CQ 3-phase PWM IC and matching control
(IRF3704S) and synchronous MOSFETs (IRF3711S).
The IRUK3055CQ01TR chipset simplifies procurement
of power MOSFETs and multi-phase, synchronous PWM
ICs to reduce design time of high current DC-DC con-
verters for CPU power. When used in a 3-phase DC-DC
converter design, the IRUK3055CQ01TR chipset can pro-
vide up to 60A for microprocessor VCORE requirements.
