The MIC4723YMME is a high-efficiency synchronous Buck DC-DC converter from Microchip Technology, designed for applications requiring up to 3A from a 3V to 5.5V input supply. It delivers an adjustable output from 1V to 5.5V, making it versatile for low-voltage logic rails. Operating at a fixed 2MHz switching frequency, it enables the use of tiny external components, saving board space. Its internal synchronous switches achieve efficiencies above 90%, reducing power loss in battery-operated and point-of-load designs. Typical applications include portable electronics, networking gear, and industrial sensors.
- High Efficiency at Light Loads: Synchronous rectification reduces diode losses, improving efficiency across the load range, especially in battery-powered devices.
- Compact Solution Size: The 2MHz switching frequency allows for small inductors and capacitors, minimizing PCB area and total BOM cost.
- Wide Adjustable Output: Output from 1V to 5.5V supports various logic levels, including 1.2V, 1.8V, and 3.3V, without external FETs.
- Thermally Enhanced Package: The exposed pad (MSOP-10) improves heat dissipation, enabling reliable operation at 3A in high-temperature environments.
Battery-Powered Portable Devices
With a 3V to 5.5V input range and 2MHz switching frequency, the MIC4723YMME is ideal for single-cell Li-Ion or multi-cell alkaline battery applications. The high frequency allows for small external inductors and capacitors, reducing PCB footprint in space-constrained designs like smartphones and wearables.
Point-of-Load (POL) Regulation for FPGAs and DSPs
Delivering up to 3A with output voltages as low as 1V, this buck converter can power core voltages of modern FPGAs and DSPs. The synchronous rectification provides high efficiency, minimizing heat dissipation in dense computing boards.
Networking and Telecom Equipment
In networking switches and routers, the 2MHz fixed frequency reduces electromagnetic interference (EMI) and enables a compact power stage. The 3A capability supports multiple I/O rails or small ASIC cores from a 5V backplane supply.
Industrial Sensor Systems
For industrial sensors operating from 3.3V or 5V rails, the MIC4723YMME provides a stable, low-ripple output. The exposed pad package enhances thermal performance, ensuring reliable operation in ambient temperatures up to 85°C.
USB-Powered Peripherals
USB ports provide 5V; this converter steps down to 1.8V, 2.5V, or 3.3V for peripheral ICs. The 3A current capability supports high-power USB devices like external storage or display adapters without overloading the port.
Distributed Power Architectures
In systems with a 5V intermediate bus, the MIC4723YMME can generate multiple lower-voltage rails. Its fast transient response (due to 2MHz switching) ensures tight regulation during dynamic load steps from digital logic.
