DESCRIPTION
The SC1406 is a High Speed, High performance Hys-
teretic Mode controller. It is part of a two chip solution,
with the SC1405 Smart Driver, providing power to ad-
vanced micro-processors. It uses a Dynamic Set Point
switching technique along with an ultra-fast compara-
tor to provide the control signal to an external high
speed Mosfet driver. A 5-bit DAC sets the output volt-
age, thus providing a voltage resolution of 25mV.
SC1406 has two on-chip linear regulators which drive
external PNP transistors with output voltage settings
of 1.5V and 2.5Vdc. The linear regulator drivers have
a separate soft start. A PWRGD TTL level signal is
asserted when all voltages are within specifications.
The part features Low Battery Detect and Undervolt-
age Lock-Out for the main Hysteretic controller to as-
sure V-DC is within acceptable limits. An Over-Current
comparator disables the main controller during an
overcurrent condition using an externally pro-
grammable threshold.
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
High efficiency distributed power supplies
