The Monolithic Power Systems MP2161GJ-P is a high-efficiency, synchronous Buck DC-DC converter designed for low-voltage applications. It operates from a 2.5V to 6V input and provides an adjustable output from 0.6V to 6V, with a maximum output current of 2A. The fixed 1.5MHz switching frequency enables the use of tiny external components, making it ideal for space-constrained designs. Available in a compact SOT-23-8 Thin package, this converter is perfect for portable electronics, wearables, and IoT devices where efficiency and small size are critical.
- High Efficiency: Synchronous rectification delivers up to 95% efficiency, extending battery life in portable devices.
- Small Solution Size: The 1.5MHz switching frequency allows for tiny inductors and capacitors, minimizing PCB area.
- Low Input Voltage (2.5V): Supports operation from single-cell Li-ion batteries down to near end-of-discharge voltage.
- High Output Current (2A): Suitable for powering application processors, FPGAs, and other power-hungry loads.
Portable Electronics
For smartphones and tablets, the MP2161's 2.5-6V input range is perfect for single-cell Li-ion batteries, efficiently stepping down to core voltages for application processors and memory.
Wearable Devices
In wearables, the small SOT-23-8 package and high 1.5MHz frequency minimize solution size, making it ideal for space-constrained designs like smartwatches and fitness trackers.
Solid-State Drives (SSDs)
SSDs require clean, efficient power for the controller and NAND flash. The MP2161 provides a compact, high-frequency solution for 3.3V and 1.8V rails.
IoT Modules
For IoT devices, this converter efficiently powers wireless SoCs and sensors from a Li-ion battery or USB supply, extending battery life with its high efficiency at light loads.
Set-Top Boxes
In consumer electronics like set-top boxes, the MP2161 steps down the 5V supply to various low-voltage rails, providing a reliable and compact power solution.
FPGA Core Supply
For small FPGAs, the 2A output current is sufficient for core logic, and the high frequency allows for a small, low-profile inductor, saving board space.
