DESCRIPTION

FEATURES

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.

APPLICATIONS

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.
