General Description

The MIC33030 is a high-efficiency, 8MHz, 400mA synchronous buck regulator with an internal inductor and HyperLight Load™ mode.

HyperLight Load™ provides very-high efficiency at light loads and ultra-fast transient response that is perfectly suited for supplying processor core voltages.

An additional benefit of this proprietary architecture is the very-low output ripple voltage throughout the entire load range with the use of small output capacitors.

Key Features

  • Internal Inductor.
  • Simplifies design to two external capacitors.
  • Input voltage: 2.7V to 5.5V.
  • Output voltage accuracy of ±2.5% over temperature.
  • 400mA output current.
  • Efficiency up to 78% at 1mA.
  • 21µA typical quiescent current.
  • Up to 8MHz PWM operation in continuous mode.
  • Ultra-fast transient response.
  • Low-voltage output ripple.
  • 30mVpp ripple in HyperLight Load™ mode.
  • 7mV output voltage r.
