Description
Power Supply Controller for Portable Pentium ® II & III SpeedStep Processors POWER MANAGEMENT .
The SC1406G PowerStep controller is a High Speed, High Performance Hysteretic Mode PWM controller.
Features
* Intel Mobile Voltage Positioning (IMVP), which increases battery life by reducing the voltage at the processor when it is heavily loaded. It also directly supports Intels SpeedStep processors for even longer battery life. A 5-bit DAC, accurate to 0.85%, sets the output voltage reference, and imple
Applications
* u Laptop and notebook computers u High performance microprocessor-based systems u High efficiency distributed power supplies
