MIC4684 is 2A High-Efficiency SuperSwitcher Buck Regulator manufactured by Micrel Semiconductor.
Micrel, Inc.
2A High-Efficiency SuperSwitcher™ Buck Regulator
General Description
The MIC4684 is a high-efficiency 200kHz stepdown (buck) switching regulator. Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. The MIC4684 achieves 2A 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...
