Product Summary

The sc451its PowerStep IV IC is a single chip high-performance Hysteretic PWM controller. With its integrated SmartDriver, it powers advanced IMVP-IV and IMVP4+ processors. The sc451its features extended Intel Mobile Voltage Positioning (IMVP to increase battery life by reducing the voltage at the processor when it is heavily loaded. It directly supports Intel SpeedStep processors for even longer battery life. The sc451its fully supports the Intel Geyserville-III core voltage specification. It provides direct deeper sleep mode and boot voltage support. Automatic power-save is present to prevent negative current flow in the low-side FET during light loading conditions, saving even more power. The high side driver initially turns on with a weak drive to reduce ringing, EMI, and capacitive turn-on of the low side.
