Features & Applications
The MIC4685WR 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 MIC4685 achieves 3 A of continuous current in the 7-lead SPAK package.
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, only the ground plane of the PCB is needed for a heat sink.
Features:
- Low 2 mm profile SPAK package
- 3 A continuous output current
- Wide 4 V to 30 V input voltage range (34 V transient)
- Fixed 200 kHz PWM operation
- Over 85% efficiency
- Output voltage adjustable to 1.235 V
- All surface mount solution
- Internally compensated with fast transient response
- Over-current protection
- Frequency foldback short-circuit protection
- Thermal shutdown
Applications:
- Point of load power supplies
- Simple high-efficiency step-down regulators
- V to 3.3 V/2 A conversion
- 12 V to 5 V/3.3 V/2.5 V/1.8 V 3 A conversion
- Dual-output ±5 V conversion
- Base stations
- LCD power supplies
- Battery chargers
