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
