W83301DR-O
1. General Description
The W83301DR-O is an ACPIcompliant controller for microprocessor and other
computer applications. The part provides functions - two switch controllers to generate a
5V
DL
and a 3.3 V
DL
voltage from ATX power supply; a linear controller – STR1 (2.5V
DUAL
),
and a bus termination controller – STR2 (1.25 V
DUAL
) for high-speed bus such as
RDRAM/DDRAM current sinking and sourcing. Besides, the W83301DR-O also can
provide extra voltage up to 0.4V in each regulator output for over-clocking application and
more performance by two hardware pins - V
SET2
, and V
SET3
. In order to reduce the
customer’ s cost, and simplify the circuit design, the W83301DR-O integrates a charge-
pump engine into the chip to provide higher driving voltage to drive single Nchannel
MOSFETs. The W83301DR-O also offers PWOK and over current detection to protect
each output and soft-start protects all linear controllers from rush current attack. The
W83301DR-O is available in a 24-pin TSSOP package.
