W83301DR-O
1. General Description
The W83301DR-O is an ACPI-compliant controller for microprocessor and other
computer applications. The part provides functions - two switch controllers to generate a
5VDL and a 3.3 VDL voltage from ATX power supply; a linear controller – STR1 (2.5VDUAL),
and a bus termination controller – STR2 (1.25 VDUAL) 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 - VSET2, and VSET3. 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 N-channel
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.
