IR3084 General Description

The IR3084 Control IC combined with an IR XPhase^TMPhase 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 XPhase^TM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.

IR3084 Maximum Ratings

Operating Junction Temperature.......0 to 150
Storage Temperature Range........−65 to 150
ESD Rating...............HBM Class 1B JEDEC standard
Moisture Sensitivity Level.........JEDEC Level 3 @ 260

IR3084 Features

• 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
