5-bit Programmable Synchronous Buck Controller Ic With Dual Ldo Controller -

The IRU3004 controller IC is specifically designed to meet Intel specifications for Pentium III 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 pat- ented 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 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 collec- tor 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 pro- grammable soft-start function as well as programming the Oscillator frequency by using an external capacitor.
