Overview
IR3536/38 Digital Multi-Phase Buck Controller CHL8326/28 FEATURES DESCRIPTION  6-phase & 8-phase dual output PWM Controller  Phases are flexibly assigned between Loops 1 & 2  Intel® VR12, AMD® 3.
4MHz SVI/PVI & Memory modes  Overclocking & 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 & Power for both loops  Non-Volatile Memory (NVM) for custom configuration  Compatible with IR ATL and 3.
3V Tri-state Drivers  +3.
3V supply voltage; -20ºC to 85ºC ambient operation  Pb-Free, RoHS...
