PRELIMINARY DATA SHEET

XPHASETM PHASE IC WITH OVP, FAULT AND OVERTEMP DETECT

DESCRIPTION

The IR3086 Phase IC combined with an IR XPhaseTM Control IC provides a full featured and flexible way to

implement power solutions for the latest high performance CPUs and ASICs. 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

• 2.5A Average Gate Drive Current

• Loss-Less Inductor Current Sense

• Internal Inductor DCR Temperature Compensation

• Programmable Phase Delay

• Programmable Feed-Forward Voltage Mode PWM Ramp

• Sub 100ns Minimum Pulse Width supports 1MHz per-phase operation

• Current Sense Amplifier drives a single wire Average Current Share Bus

• Current Share Amplifier reduces PWM Ramp slope to ensure sharing between phases

• Body BrakingTM disables Synchronous MOSFET for improved transient response and prevents negative

output voltage at converter turn-off

• OVP comparator with 150ns response

• Phase Fault Detection

• Programmable Phase Over-Temperature Detection

• Small thermally enhanced 20L MLPQ package
