Product Overview
The MIC4684YM is a high-efficiency SuperSwitcher™ Buck Regulator for use with battery charger. Power conversion efficiency of above 85% is easily obtainable for a wide variety of applications. The MIC4684 achieves 2A of continuous current 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. It allows for a high degree of safety. It has a wide input voltage range of 4 to 30V (34V transient), allowing it to be used in applications where input voltage transients may be present. Built-in safety features include overcurrent protection, frequency-foldback short-circuit protection and thermal shutdown.
- All surface mount solution
- Internally compensated with fast transient response
- Over 85% efficiency
