US3033 - PWM SWITCHER & LINEAR CONTROLLER IC

Datasheet Summary

Description

The US3033 IC combines a switching controller and a linear regulator controller all in a compact 8 pin surface mount package, providing a total solution for dual supply processor applications such as an Intel P55C ™, AMD K6™, as well as Cyrix 6X86L™ and the M2™processors.

Features

  • LDO Controller allows the use of a low cost pass transistor for the I/O supply 8 pin SOIC combines switching and linear controller Internal Pre-regulator Eliminates Cross talk between Switching & Linear regulators Automatic shut down of the linear regulator when connected to the Vcc2 Det pin On board MOSFET driver Fastest transient response of any controller method. ( 0 to 100% Duty Cycle in 100 nS ) 1% internal voltage reference Internal Under Voltage Lockout protects MOSFET during start-up DE.
