The CHL8225/8 NVM saves pins and enables a small package size. The CHL8225/8 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 as a function of real-time load current. CHiL Dynamic Phase Control adds and drops phases based upon load current. The CHL8225/8 can be configured to enter 1-phase operation and active diode emulation mode based upon load current or by command. CHiL’s unique Adaptive Transient Algorithm ATA , based on proprietary non-linear digital PWM algorithms, minimizes output bulk capacitors. In addition, a coupled inductor mode, with phases added/dropped in pairs enables further improvement in transient response and form factor. The I2C/PMBus interface can communicate with up to 16 CHL8225/8 based VR loops.
