IRU3034
8-PIN PWM SWITCHER CONTROLLER IC
WITH CURRENT LIMITING
DESCRIPTION
The IRU3034 IC provides a low cost switching controller
with true short circuit protection all in a compact 8-pin
surface mount package, providing a low cost switching
solution for dual supply processor applications that re-
quire switching regulator for the 3.3V supply such as
the applications with AGP on-board. Typically in these
applications, a dual supply regulator converts 5V to 3.3V
for I/O supply and a jumper programmable supply of
1.25V to 3.5V for Core supply. 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 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.
FEATURES
8-Pin SOIC switching controller with
HICCUP current limiting reduces diode power
dissipation to less than 1% of normal operation
Soft-Start capacitor allows for smooth output
voltage ramp up
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鈩?, CYRIX M2鈩?, POWER PC鈩?and
AMD K6鈩?/div>
Simple 5V to 3.3V switcher for Pentium with AGP
or Pentium II鈩?applications
