The MP2161AGJ-P from Monolithic Power Systems is a high-efficiency, synchronous step-down (Buck) converter designed for space-constrained applications. It operates from a 2.5V to 6V input supply and delivers up to 2A of output current. The 1.5MHz fixed switching frequency enables the use of tiny inductors and capacitors, minimizing the overall solution footprint. With an adjustable output from 0.6V, it is well-suited for powering low-voltage cores in portable electronics, SSDs, and industrial sensors.
- High Efficiency: Synchronous rectification improves efficiency, reducing heat dissipation in battery-powered devices.
- Compact Solution Size: The 1.5MHz switching frequency allows for small, low-profile external components, saving PCB area.
- Wide Adjustable Output: Output can be set from 0.6V to 6V, providing flexibility for various low-voltage rails.
- Small Package: The TSOT-23-8 package is ideal for space-limited designs.
