CHL8326

CHL8326 :  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 Temperatu.

CHL8328 : The CHL8326/8 are dual-loop digital multi-phase buck controllers. The CHL8326 drives up to 6 phases and the CHL8328 drives up to 8 phases. The CHL8326/8 is fully Intel® VR12 and AMD® SVI/PVI compliant on both loops and provides a Vtt tracking function for DDR memory. NVM storage saves pins and enables a small package size. The CHL8326/8 includes the CHiL Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. CHiL Variable Gate Drive optimizes the MOSFET gate drive voltage based on realtime load current. CHiL Dynamic Phase Control adds/drops phases based upon load current. The CHL8326/8 can be configured to enter 1-phase operation and act.
