MIC2230 - Dual Synchronous 800mA/800mA Step-Down DC/DC Regulator

General Description

The MIC2230 is a dual output, high-efficiency synchronous step-down DC/DC converter.

The MIC2230 is ideally suited for portable and embedded systems that demand high power conversion efficiencies and fast transient performance, while offered in a very small package.

Key Features

  • High Efficiency: Over 96%.
  • Ultra-Low Quiescent Current: Only 28 μA.
  • Ultra-Low Shutdown Current: Less Than 1 μA.
  • Fast Transient Performance.
  • 2.5 MHz PWM Operation.
  • High Output Current Capability per Channel: 800 mA.
  • No Schottky Diodes Required.
  • Stable with 2.2 μH Inductor, 10 μF Ceramic Capacitor.
  • Adjustable Output Voltage Down to 0.8V.
  • Built-In Soft-Start Circuitry.
  • Current-Limit Protection.
