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 SpeedStep™ 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, sav.
