APPLICATION NOTE FOR SC1406A
INTRODUCTION
DESCRIPTION
The SC1406A is a High Speed, High perfor-
mance 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.
SC1406A has two on-chip linear regulators
which drive external PNP transistors with out-
put 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 Un-
dervoltage Lock-Out for the main Hysteretic
controller to assure V-DC is within acceptable
limits. An Over-Current comparator disables
the main controller during an overcurrent
condition using an externally programmable
threshold.
APPLICATIONS
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
FEATURES
Laptop and Notebook computers
High performance Microprocessor based
systems
High efficiency distributed power supplies
