Micrel MIC4684
The MIC4684 is a high-efficiency 200kHz stepdown (buck) switching regulator. The MIC4684 achieves 2A of continuous current in an 8-lead SO (small outline) package at 60°C ambient temperature. The MIC4684, housed in an SO-8, can replace larger TO-220 and TO-263 packages in many applications.- Min Voltage : 4V
- Max Voltage : 30V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C

GENERAL DESCRIPTION
Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. 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 allows for a high degree of safety. It has a wide input voltage range of 4V to 30V (34V transient), allowing it to be used in applications where input voltage transients may be present. Built-in safety features include over-current protection, frequency
