IR3505 Datasheet Phase

Manufacturer: International Rectifier (now Infineon)

Overview: IR3505 DATA SHEET XPHASE3TM PHASE IC.

General Description

The IR3505 Phase IC combined with an IR XPhase3 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 TM phase of a multiphase converter.

The XPhase3 architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches.

Key Features

  • 7V/2A gate drivers (4A GATEL sink current) Support converter output voltage up to 5.1 V (Limited to VCCL-1.4V) Support loss-less inductor current sensing Feed-forward voltage mode control Integrated boot-strap synchronous PFET Only four IC related external components per phase 3 wire analog bus connects Control and Phase ICs (VDAC, Error Amp, ISHARE) 3 wire digital bu.
