When it comes to powering today's portable electronics, efficiency, size, and performance are non-negotiable. AXTEK Technology proudly introduces the AX2412, a 1.5MHz, 1A step-down (buck) converter designed to deliver stable power in compact, battery-powered systems.

Why AX2412?

The AX2412 is built with the needs of portable and space-constrained applications in mind. Operating with a constant 1.5MHz switching frequency, it supports an input voltage range of 2.5V to 5.5V and regulates output voltages as low as 0.61V, all while delivering up to 1A of output current. Whether you're designing for a smartphone, GPS device, or DSP core, the AX2412 offers the efficiency and flexibility you need.

Designed for Real-World Demands

The AX2412 offers 100% duty cycle operation in dropout mode, enabling maximum battery usage—essential for products where every minute of run time counts. Its low shutdown current (<1µA) and soft-start feature help preserve battery life and ensure smooth power-up behavior, while short circuit and thermal protection add robust reliability.

Thanks to its current-mode PWM architecture with built-in slope compensation, the AX2412 allows the use of smaller inductors, reducing BOM cost and saving board space without compromising performance.
