Features & Applications

The MIC4684YM is a high-efficiency 200 kHz stepdown (buck) switching regulator. Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. The MIC4684 achieves 2 A of continuous current in an 8-lead SO (small outline) package at 60°C ambient temperature.

High efficiency is maintained over a wide output current range by utilizing a boost capacitor to increase the voltage available to saturate the internal power switch. As a result of this high efficiency, no external heat sink is required. The MIC4684, housed in an SO-8, can replace larger TO-220 and TO-263 packages in many applications.

Features:

  • SO-8 package with 2 A continuous output current
  • Over 85% efficiency
  • Fixed 200 kHz PWM operation
  • Wide 4 V to 30 V input voltage range
  • Output voltage adjustable to 1.235 V
  • All surface mount solution
  • Internally compensated with fast transient response
  • Over-current protection
  • Frequency foldback short-circuit protection
  • Thermal shutdown 

Applications:

  • Simple high-efficiency step-down regulator
  • 5 V to 3.3 V/1.7 A converter (60°C ambient)
  • 12 V to 1.8 V/2 A converter (60°C ambient)
  • On-card switching regulator
  • Dual-output ±5 V converter
  • Battery charger
