8-PIN PWM SWITCHER AND LINEAR CONTROLLER IC
FEATURES
LDO Controller allows the use of a low cost pass
transistor for the I/O supply
8-Pin SOIC combines switching and linear
controller
Internal pre-regulator eliminates cross talk
between switching and linear regulators
Automatic shut down of the linear regulator when
connected to the Vcc2 detect pin
On-Board MOSFET Driver
Fastest transient response of any controller
method (0 to 100% Duty Cycle in 100ns)
1% Internal Voltage Reference
Internal Under-Voltage Lockout protects MOSFET
during start-up
APPLICATIONS
Dual supply low voltage processor applications,
such as: P55C ? , CYRIX M2 ? , POWER PC ?
and AMD K6 ?
Simple 5V to 3.3V switcher for Pentium with AGP
or Pentium II ? applications

DESCRIPTION
The IRU3033 IC combines a switching controller and a
linear regulator controller all in a compact 8-pin surface
mount package, providing a total solution for dual sup-
ply processor applications such as an Intel P55C ? , AMD
K6 ? , as well as Cyrix 6X86L ? and the M2 ? proces-
sors. Typically in these applications a dual supply regu-
lator converts 5V to 3.3V for I/O supply and a jumper
programmable supply of 1.25V to 3.5V for Core supply.
The linear regulator controller portion in the IRU3033 is a
programmable controller allowing flexibility for the I/O
regulator and has a minimum of 50mA drive current ca-
pability designed to provide ample current for an exter-
nal pass transistor. The IC uses an internal regulator
generated from the 12V supply to power the controller
as well as the 12V supply to drive the power MOSFET,
allowing a low cost N-channel MOSFET switch to be
used. The IC also includes an error comparator for fast
transient response, a precise voltage reference for set-
ting the output voltage as well as a direct drive of the
MOSFET for the minimum part count.
