5-bit Programmable Synchronous Buck Plus Ldo Controller And 200ma Ldo On-board - International Rectifier

The IRU3018 controller IC is specifically designed to meet Intel specification for Pentium II Microprocessor appli- cations as well as the next generation of P6 family pro- cessors. The IRU3018 provides a single chip controller IC for the Vcore, LDO controller for GTL+ and an internal 200mA Regulator for Clock supply which are required for the Pentium II applications. These devices feature a pat- ented topology that in combination with a few external components as shown in the typical application circuit, will provide in excess of 18A of output current for an on- board DC-DC Converter while automatically providing the right output voltage via the 5-bit internal DAC The IRU3018 also features loss-less current sensing for both switchers by using the RDS(on) of the high-side power MOSFET as the sensing resistor, internal current limit- ing for the Clock supply, and a Power Good window com- parator that switches its Open Collector output low when any one of the outputs is outside of a pre-programmed window. Other features of the device are: Under-voltage lockout for both 5V and 12V supplies, an external pro- grammable soft-start function, programming the oscilla- tor frequency via an external resistor, Over-Voltage Pro- tection (OVP) circuitry for both switcher outputs and an internal thermal shutdown.
