DESCRIPTION
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 R DS(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.
