IR3536A
Overview
Dual Loop, 5+1 multiphase VR12/AMD PWM controller for high efficiency, highly accurate VR solutions
Benefits
- 8-phase dual output PWM Controller
- Phases are flexibly assigned between Loops 1 and 2
- Intel® VR12, AMD® 3.4MHz SVI/PVI and Memory modes
- Overclocking and Gaming Mode with Vmax setting
- Switching frequency from 200kHz to 1.2MHz per phase
- IR Efficiency Shaping Features including Variable Gate Drive and Dynamic Phase Control
- Programmable 1-phase or 2-phase for Light Loads and Active Diode Emulation for Very Light Loads
- 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
- Non-Volatile Memory (NVM) for custom configuration
