The SC1474 PowerStep IIITM IC is a single chip high-performance Hysteretic PWM controller. With dual integrated SmartTM Drivers, it powers advanced Pentium 4 processors. The SC1474 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's SpeedStepTM requirements for even longer battery life. The SC1474 automatically detects performance and battery mode VIDs. In addition, it integrates direct "deeper sleep" mode support. All operating modes incorporate automatic "power-save" to prevent negative current flow in the low-side FET during light loading conditions, saving even more power.
