Ordering Information
General Description
The RT9174 is a triple linear regulator controller designed
for motherboard application.
The regulators are intended to regulate the computer
system AGP (2X/4X) power, the 2.5V clock power, and the
1.8V power for North/South Bridge core voltage and/or cache
memory circuits. All controllers can drive NPN or
NMOSFET pass transistor. A special scheme employing
driver voltage could be higher than V
DD
when driving
NMOSFET through the 12V power.
The RT9174 future a small SOP-8 package for saving board
area. It also builds in current limiting and thermal shutdown
protection function.
