The MIC4722YML is a high-efficiency synchronous buck converter from Micrel, capable of delivering up to 3A. It accepts inputs from 2.7V to 5.5V and provides an adjustable output from 1V to 5.5V. Operating at 2.7MHz, it enables the use of very small external components, making it perfect for space-limited designs. The 12-MLF package ensures low thermal resistance for reliable high-current operation in portable and industrial applications.
- 3A output current: Handles high-power loads in compact devices.
- 2.7MHz switching: Minimizes external component size and PCB footprint.
- Wide 2.7V-5.5V input: Works with single-cell Li-ion and standard 5V rails.
- Adjustable output to 5.5V: Flexible for various voltage requirements.
- MLF package: Superior thermal performance for sustained high current.
High-Current Portable Devices
For tablets and handheld gaming consoles, the MIC4722YML provides up to 3A from a single Li-ion cell. Its 2.7MHz frequency allows a very compact solution while maintaining high efficiency.
Distributed Power Systems
In systems with 3.3V or 5V intermediate buses, this converter generates lower voltages for FPGAs and ASICs. The adjustable output up to 5.5V also supports I/O rails.
Networking and Communication
For wireless access points and switches, the MIC4722YML powers high-current digital loads. The MLF package provides excellent thermal performance for continuous operation.
Industrial Sensors and Actuators
With a 5V supply, this buck converter can drive 3.3V logic and 2.5V analog circuits. Its high frequency reduces output ripple, critical for precision measurement.
Battery-Powered Medical Devices
In portable medical equipment, the wide input range and 3A output support motors, displays, and processors, all from a single battery pack.
