XPHASE
TM
VR 10.0 CONTROL IC
DESCRIPTION
The IR3081 Control IC combined with an IR
XPhase
TM
Phase IC provides a full featured and flexible way
to implement a complete VR 10.0 power solution. The “Control” IC provides overall system control and
interfaces with any number of “Phase ICs” which each drive and monitor a single phase of a multiphase
converter. The X
Phase
architecture results in a power supply that is smaller, less expensive, and easier
to design while providing higher efficiency than conventional approaches.
The IR3081 is intended for VRD or VRM/EVRD 10.0 applications that use external VCCVID/VTT circuits.
FEATURES
6 bit VR 10.0 compatible VID with 0.5% overall system accuracy
Programmable Dynamic VID Slew Rate
No Discharge of output capacitors during Dynamic VID step-down (can be disabled)
+/-300mV Differential Remote Sense
Programmable 150kHz to 1MHz oscillator
Programmable VID Offset and Load Line output impedance
Programmable Softstart
Programmable Hiccup Over-Current Protection with Delay to prevent false triggering
Simplified Powergood provides indication of proper operation and avoids false triggering
Operates from 12V input with 9.1V Under-Voltage Lockout
6.8V/5mA Bias Regulator provides System Reference Voltage
Enable Input
Small thermally enhanced 28L MLPQ package
