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 supply for the I/O plane and a 1.515V power supply for the GTL+ and AGP planes. The SC1538CS25/25 can provide two 2.525V supplies for clock and memory.

SC1538 features include Enable controls for each lin ear FET controller and over current protection. Overcurrent protection is provided by feedback to the sensepins. 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.
