W83301DR-O

The W83301DR-O is an ACPI-compliant 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 VS_ET3. In order to reduce the customer's cost, and simplify the circuit design, the W83301DR-O integrates a chargepump 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.
