Overview

MIC4685 Micrel MIC4685 3A SPAK SuperSwitcher™ Buck Regulator Final General Description The MIC4685 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 MIC4685 achieves 3A of continuous current in the 7-lead SPAK package.
The thermal performance of the SPAK allows it to replace TO-220s and TO-263s (D2 PAKs) in many applications.
The SPAK saves board space with a 36% smaller footprint than TO-263.
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 ...
