IR3086APBF XPHASETM PHASE IC

The IR3086APbF 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 XPhaseT.

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.
