The MIC4723YML from Micrel is a high-frequency synchronous buck DC-DC converter designed for space-constrained, battery-powered applications. It accepts an input voltage from 2.7V to 5.5V and provides an adjustable output from 1V to 5.5V, delivering up to 3A of continuous current. The fixed 2MHz switching frequency enables the use of tiny external components, reducing the overall solution footprint. Housed in a 12-MLF® package with an exposed pad for thermal management, this converter is ideal for point-of-load regulation in portable electronics, computing, and industrial systems.
- High Efficiency: Synchronous rectification minimizes power loss, extending battery life in portable devices.
- Compact Solution: 2MHz switching frequency allows small inductors and capacitors, saving board space.
- High Output Current: 3A capability supports power-hungry processors and FPGAs.
- Wide Adjustable Output: 1V to 5.5V range provides flexibility for various logic and analog rails.
- Thermally Enhanced Package: Exposed pad in MLF package improves heat dissipation for reliable operation.
Point-of-Load (POL) Regulation for FPGAs and ASICs
Convert a 5V or 3.3V system rail down to a core voltage (e.g., 1.2V, 1.8V) with up to 3A. The 2MHz switching frequency allows the use of small inductors and capacitors, saving PCB space in dense digital designs.
Portable Battery-Powered Devices
Step down a Li-Ion battery voltage (2.7V-4.2V) to a stable 1.8V or 3.3V rail. The high efficiency of the buck converter extends battery life in smartphones, wearables, and handheld instruments.
Distributed Power Systems
Provide a local regulated supply from a 5V bus in networking equipment. The 3A current capability supports multiple loads, while the exposed pad package aids thermal dissipation.
Automotive Infotainment
Regulate 5V from a vehicle's USB power supply (5V) or from a 3.3V logic rail. The wide input range accommodates voltage transients, ensuring reliable operation of displays and audio processors.
Industrial Sensor Nodes
Power 3.3V microcontrollers and sensors from a 5V fieldbus supply. The 2MHz frequency reduces output ripple, improving ADC accuracy in industrial monitoring systems.
Computing Peripherals
Supply low-voltage rails for SSDs, memory modules, and interface controllers. The compact MLF package and high frequency enable slim form-factor designs.
