MIC4684 - 2A High Efficiency Buck Regulator

General Description

The MIC4684 is a high-efficiency 200 kHz step-down (buck) switching regulator.

The MIC4684 achieves up to 2A of continuous current in an 8-lead SOIC (small outline) package at 60°C ambient temperature.

As a result of high efficiency, no external heat sink is required.

Key Features

  • Up to 2A Continuous Output Current.
  • Up to 85% Efficiency.
  • Fixed 200 kHz PWM Operation.
  • Wide 4V to 30V Input Voltage Range.
  • Output Voltage Adjustable to 1.235V.
  • Internally Compensated with Fast Transient Response.
  • Overcurrent Protection.
  • Frequency Foldback Short-Circuit Protection.
  • Thermal Shutdown.
