DESCRIPTION
The US2075 is a dual function IC combining a switching
controller and a 7.5A low dropout regulator all in a
com-
pact 7 pin TO220
and TO263 surface mount
pack-
ages providing a
total solution
for dual supply proces-
sor applications such as an
Intel P55C
, AMD K6
,
as well as Cyrix 6X86L
and the M2
processors.
Typically in these applications a dual supply regulator
converts 5V to 3.3V for I/O supply and a jumper pro-
grammable supply of 2.8V to 3.5V for CORE supply .The
linear regulator portion in the US2075 is a fixed 3.30V
output and has a minimum of 7.5A current capability
designed to provide ample current for most applications
while the switching regulator controller uses the 5V sup-
ply to power the controller and the 12V supply to drive
the power MOSFET, allowing a low cost N- MOS switch
to be used. The IC also includes an error comparator for
fastest transient response, a precise voltage reference
for setting the output voltage as well as a direct drive of
the MOSFET for the minimum part count.
FEATURES
The US2075 eliminates the need for a
seperate switching controller IC
Minimum part count allows lower system cost
Fixed 3.30V/7.5A LDO on board
On board MOSFET driver
Fastest transient response of any controller
method. ( 0 to 100% Duty Cycle in 100 nS )
1% internal voltage reference
Internal Thermal shutdown
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
