XPHASETM VR 10/11 CONTROL IC
DESCRIPTION
The IR3084A Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible
way to implement a complete VR10 or VR11 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 XPhaseTM architecture results in a power supply that is smaller, less
expensive, and easier to design while providing higher efficiency than conventional approaches.
FEATURES
www.DataSheet4U.com
1 to X phase operation with matching Phase IC
Supports both VR11 8-bit VID code and extended VR10 7-bit VID code
0.5% Overall System Setpoint Accuracy
VID Select pin sets the DAC to either VR10 or VR11
VID Select pin selects either VR11 or legacy VR10 type startups
Programmable VID offset and Load Line output impedance
Programmable VID offset function at the Error Amp’s non-inverting input allowing zero offset
Programmable Dynamic VID Slew Rate
±300mV Differential Remote Sense
Programmable 150kHz to 1MHz oscillator
Enable Input with 0.85V threshold and 100mV of hysteresis
VR Ready output provides indication of proper operation and avoids false triggering
Phase IC Gate Driver Bias Regulator / VRHOT Comparator
Operates from 12V input with 9.9V Under-Voltage Lockout
6.9V/6mA Bias Regulator provides System Reference Voltage
Programmable Hiccup Over-Current Protection with Delay to prevent false triggering
Small thermally enhanced 5mm x 5mm, 28 pin MLPQ package
