MIC23051 - 4MHz PWM Buck Regulator

General Description

The MIC23051 is a high efficiency 600 mA PWM synchronous buck (step-down) regulator featuring HyperLight Load®, a patented switching scheme that offers best in class light load efficiency and transient performance while providing very small external components and low output ripple at all loads.

Key Features

  • Input Voltage: 2.7V to 5.5V.
  • 600 mA Output Current.
  • Fixed Output Voltage 1.25V, 1.2V, 1.4V and 1.8V with Voltage Scaling Down Using VSC pin to: 0.95V, 1.0V, 1.15V and 1.0V.
  • Ultra-Fast Transient Response.
  • 20 µA Typical Quiescent Current.
  • 4 MHz CCM PWM Operation in Normal Mode.
  • 0.47 µH to 2.2 µH Inductor.
  • Low Voltage Output Ripple - 25 mVPP Ripple in HyperLight Load® Mode - 3 mV Output Voltage Ripple in Full PWM Mode.
