Description	Portable Pentium Dual Phase Power Supply Controller
Datasheet	SC1474_SemtechCorporation.pdf

The SC1474 PowerStep III™ IC is a single chip high-performance Hysteretic PWM controller.

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.
