DESCRIPTION
The SC1406A is a High Speed, High performance Hysteretic Mode controller. It is part of a two chip solution, with the SC1405 Smart Driver, providing power to advanced micro-processors. It uses a Dynamic Set Point switching technique along with an ultra-fast comparator to provide the control signal to an external high speed Mosfet driver. A 5-bit DAC sets the output voltage, thus providing a voltage resolution of 25mV.

FEATURES
• High Speed Hysteretic controller provides high efficiency over a wide operating load range
• Inherently stable
• Complete power solution with two LDO drivers
• Programmable output voltage for Pentium® II & III Processors

APPLICATIONS
• Laptop and Notebook computers
• High performance Microprocessor based systems
