DESCRIPTION
The IRU3013 controller IC is specifically designed for
Intel Pentium III ? microprocessor applications as de-
scribed in the VRM 8.5 specification. The IC provides
a single chip solution for the Vcore, 1.2V AGTL+,
1.8V and a third uncommitted LDO controller that
can be used either as 1.2V power good detector or
to provide 1.5V AGP bus in applications that this
voltage is required. The IRU3013 features a patented
topology that, in combination with a few external com-
ponents, (*Note: See application current in Figure 3) will
provide in excess of 30A of output current for an on-
board Vcore synchronous converter while automatically
providing the output voltage specified in VRM 8.5 speci-
fication. The IRU3013 also features, loss-less current
sensing by using the R DS(ON) of the high side Power
MOSFET as the sensing resistor , a Power Good win-
dow comparator that switches its open collector output
low when the output is outside of a ± 10% window. Other
features of the device are: Under-voltage lockout for both
5V and 12V supplies, an external programmable soft-
start function, and the ability to program the oscillator
frequency by connecting an external capacitor.
