SMB_DAT  Per-Loop Fault Protection: OVP, UVP, OCP ISEN 3  IR Adaptive Transient Algorithm (ATA) on both loops minimizes output bulk capacitors and system cost The CHL8102/03/04/13 provides extensive OVP, UVP, OCP and OTP fault protection and the CHL8103/04/13 includes thermistor based temperature sensing with VRHOT signal. IRTN4 (CHL8104)/ NC (CHL8103)  1-phase & Active Diode Emulation modes for light load efficiency ADDR/PROT/EN_L2  IR Efficiency Shaping with Dynamic Phase Control (DPC) IRTN 3  Independent loop switching frequencies from 200kHz to 1.2MHz per phase ENABLE  I2C security enable pin (CHL8103/04/13) IR’s unique Adaptive Transient Algorithm (ATA), based on proprietary non-linear digital PWM algorithms, minimizes output bulk capacitors and Multiple Time Programmable (MTP) storage saves pins and enables a small package size. Device configuration and fault parameters are easily defined using the IR Digital Power Design Center (DPDC) GUI and stored in on-chip MTP. ISEN 2  Flexible I2C bus security features VR_HOT#  Overclocking support with I2C voltage override and Vmax setting IRTN 2  Pin programmable I2C address (CHL8103/04/13) SV_DAT1/SVD2  I2C interface for configuration & telemetry The CHL8102/03/04/13 includes IR Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Dynamic Phase Control adds/drops active phases based upon load current and can be configured to enter 1-phase operation and diode emulation mode automatically or by command. ISEN 1  Fully supports Intel® VR12 (CHL8103/04/13) and AMD® SVI with dual OCP & programmable addressing (CHL8103/04) SV_CLK1/SVC2  Footprint compatible with CHL8325A/B (CHL8103/4) IRTN 1  Easiest layout and fewest pins in the industry The CHL8102/03/04 are dual-loop, digital multi-phase buck controllers designed for CPU voltage regulation. The CHL8113 is a single-loop, digital multiphase buck controller ideal for Server DDR memory voltage regulation. They are fully compliant with the Intel® VR12 and AMD® SVI (CHL8103/04) specifications.
