IR3570B

Überblick

Dual Loop, 3+2 multiphase AMD SVI1 and SVI2 and Intel VR12 and VR12.5 PWM controller for high efficiency, highly accurate VR solutions

Vorteile

  • Dual output 4+1 and 3+2 phase PWM Controllers
  • Easiest layout and fewest pins in the industry
  • Fully supports AMD® SVI1 and SVI2 with dual OCP and Intel® VR12 and VR12.5
  • Complies with VR12.5 Rev 1.3 requirement for SVID register 15h to have <200 µSec filter
  • Overclocking and Gaming Mode
  • Switching frequency from 200kHz to 2MHz per phase
  • IR Efficiency Shaping Features including Dynamic Phase Control and Automatic Power State Switching
  • IR Adaptive Transient Algorithm (ATA) on both loops minimizes output bulk capacitors and system cost
  • Auto-Phase Detection with auto-compensation
  • Per-Loop Fault Protection: OVP, UVP, OCP, OTP, CFP
  • I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current and Power for both loops
  • Multiple Time Programming (MTP) with integrated charge pump for easy custom configuration
  • Compatible with IR ATL and 3.3V tri-state Drivers
  • +3.3V supply voltage -40°C to 85°C ambient operation
  • Pb-Free, RoHS, 5x5mm, 40-pin, 0.4mm pitch QFN
