SC1406G  
Power Supply Controller for Portable  
®
Pentium II & III SpeedStep™ Processors  
POWER MANAGEMENT  
Features  
Description  
The SC1406G PowerStep™ controller is a High Speed,  
High Performance Hysteretic Mode PWM controller.  
Teamed with the SC1405 Smart™ Driver, it powers ad-  
vanced Pentium® II and Pentium® III processors. The  
SC1406G features Intel Mobile Voltage Positioning  
(IMVP), which increases battery life by reducing the volt-  
age at the processor when it is heavily loaded. It also  
directly supports Intel’s SpeedStep™ processors for even  
longer battery life.  
u High-speed hysteretic controller provides high effi  
ciency over a wide operating load range  
u Inherently stable  
u Complete CPU power solution with two LDO drivers  
u Programmable core voltage for Pentium® II & III pro  
cessors  
u Native Speed Step® support  
Applications  
A 5-bit DAC, accurate to 0.85%, sets the output voltage  
reference, and implements the 0.925V to 2.00V range  
of the mobile Pentium® specifications. The hysteretic  
converter uses a comparator without an error amplifier,  
and therefore provides the fastest possible transient  
response, while avoiding the stability issues inherent to  
classical PWM controllers.  
u Laptop and notebook computers  
u High performance microprocessor-based systems  
u High efficiency distributed power supplies  
Two linear regulator controllers, coupled with appropri-  
ate external transistors, produce tightly regulated 1.5V  
and 2.5V to complete the processor power solution.  
The SC1406G also features separate soft-start con-  
trols for the converter and the regulators, a TTL-  
compatible power good indication, logic enable, and  
low battery undervoltage lockout. Programmable  
current limiting uses a separate comparator to protect  
against overloads and short-circuits.
