DESCRIPTION
The US3034 IC provides an 8 pin low cost switching controller with true short circuit protection all in a compact 8 pin surface mount package, providing a low cost switching solution for dual supply processor applications that require switching regulator for the 3.3V supply such as the applications with AGP on board.
   
FEATURES
■ 8 pin SOIC Switching Controller with
    HICCUP Current Limiting Reduces Diode
    Power Dissipation to Less than 1% of Normal
    Operation
■ Soft Start Capacitor allows for smooth Output
    Voltage ramp up
■ 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
   
APPLICATIONS
■ Dual supply low voltage processor applications,
    such as: P55Cä,CYRIX M2ä, POWER PCä and
    AMD K6ä
■ Simple 5V to 3.3V switcher for Pentium with AGP
    or Pentium IIä applications
