IRU3004 General Description
The IRU3004 controller IC is specifically designed to meet Intel specifications for Pentium IIIä microprocessor applications as well as the next generation P6 family processors. The IC provides a single chip controller IC for the Vcore, GTL+ and clock supplies required for the Pentium III applications. The IRU3004 features a patented topology, that in combination with a few external components as shown in the typical application circuit, will provide in excess of 20A of output current for an onboard DC-DC converter while automatically providing the right output voltage via the 5-bit internal DAC meeting the latest VRM specification. The IRU3004 also features loss-less current sensing by using the RDS(on) of the high side power MOSFET as the sensing resistor and a Power Good window 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 as well as programming the oscillator frequency by using an external capacitor.
