DESCRIPTION
The SC1538 is a dual power supply controller designed
to simplify power management on motherboards. It is
part of Semtech’s Smart LDO family of products.
The SC1538CS15/18 can provide a 1.818V power sup-
ply for the I/O plane and a 1.515V power supply for the
GTL+ and AGP planes. The SC1538CS25/25 can pro-
vide two 2.525V supplies for clock and memory.
SC1538 features include Enable controls for each lin-
ear FET controller and over current protection. Over
current protection is provided by feedback to the sense
pins. If any output drops below 1V (typical) for greater
than 4ms (typical), that output will shut down.
The SC1538 is available in a SO-8 surface mount
package.
