IRU3034CSTR Description

The IRU3034CSTR is an 8-pin PWM Switcher Controller IC with current limiting.

IRU3034CSTR 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 100ns)

• 1% Internal Voltage Reference

• Internal Under-Voltage Lockout protects MOSFET during start-up

IRU3034CSTR Applications

• Dual supply low voltage processor applications, such as P55CTM, CYRIX M2TM, and POWER PCTM. and AMD K6TM

• Simple 5V to 3.3V switcher for Pentium with AGP or Pentium |ITM applications
