Product Summary
The US3004CW is a 5 bit programmable synchronous buck controller. It can be used in (1)Pentium III & next generation processor DC to DC converter application; (2)Low cost Pentium with AGP. The IC provides a single chip controller IC for the Vcore , GTL+ and clock supplies required for the Pentium III applications. Also it features less current sensing by using the Rds-on of the high side Power MOSFET as the sensing resistor, a Power Good window comparator that switches its open collector output low when the output is outside of a ±10% window.
Parametrics
US3004CW absolute maximum ratings: (1)V5 supply Voltage: 10V; (2)V12 Supply Voltage: 20V; (3)Storage Temperature Range: -65 TO 150°C (4)Operating Junction Temperature Range: 0 To 125°C.
Features
US3004CW features: (1)Meets Latest VRM 8.4 Specification for PIII Provides Single Chip Solution for Vcore, GTL+ and Clock Supply On board DAC programs the output voltage from 1.3V to 3.5V ; (2)The US3004/5 remains on for VID code of (11111); (3)Dual linear regulator controller on board for 1.5V GTL+ and 2.5V clock supplies; (4)Loss less Short Circuit Protection; (5)Synchronous operation allows maximum efficiency; (6)Patented architecture allows fixed frequency operation as well as 100% duty cycle during dynamic load; (7)Min part count, No external Compensation; (8)Soft Start; (9)High current totem pole driver for direct driving of the external Power MOSFET; (10)Power Good function.
