IRU3011 General Description

The IRU3011 controller IC is specifically designed to meet Intel specification for latest Pentium III™ microprocessor applications as well as the next generation P6 family processors. These products feature 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 on-board DC/DC converter while automatically providing the right output voltage via the 5-bit internal DAC. These devices 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 window comparator that switches its open collector output low when the output is outside of a ±10% window and an Over-Voltage Protection output. 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.
